SINGAPORE: The gala felt straight out of the movie “Crazy Rich Asians.” In this tropical-island nation famously dense with millionaires, 600 guests gathered in September 2023 to fete one of Singapore’s most prominent success stories: the property empire that owns the global Millennium hotel chain and the Biltmore Los Angeles.
The politicians, business leaders and foreign envoys in attendance heaped praise on the company’s octogenarian executive chairman, Kwek Leng Beng , who built a family fortune estimated at $11.5 billion and made deals with the likes of Donald Trump. Guests at the black-tie dinner savoured abalone, bird’s nest soup and lobster, while dancers and musicians performed on a stage.
At the head table, the tycoon, clad in a blue tuxedo, reigned with his wife, Cecilia.
But there was another woman in the ballroom, wearing a red dress, whose presence wasn’t welcome to some in the family.
Catherine Wu, a Juilliard-trained pianist and former television host in her native Taiwan, was well-known to company executives for her close relationship with the chairman. Senior executives had long bristled at what they saw as her interference in the hotel business, according to people familiar with the matter. But until this moment, she had largely shunned the limelight and avoided public company events. The internal complaints about her outsize influence remained unknown to the public.
Now Wu was thrusting herself into the spotlight, introducing herself to the dignitaries—including Singapore’s prime minister-in-waiting—and posing for photos with them. Onlookers blanched. People sympathetic to Cecilia Kwek and concerned about Wu’s influence at the company thought Wu, by attending the gala, had crossed a line.
Earlier this year, the tensions that seethed at the event burst into the open.
The chairman’s elder son and chosen successor, Sherman Kwek, 49, and his allies moved to add new directors to the board, a manoeuvre he later said was meant to eliminate Wu’s influence at the family business, called City Developments Ltd., or CDL for short.

“She has been interfering in matters going well beyond her scope, and she wields and exercises enormous influence,” Sherman Kwek said in a statement on behalf of the majority of the board, issued in February after the feud erupted into public view. “Due to her long relationship with the chairman, efforts that were made to manage the situation were done sensitively, but to no avail.”
Kwek Leng Beng fought back by trying to dismiss his son as chief executive and suing him for allegedly trying to usurp power—something that Sherman denies. The elder Kwek later said Wu had contributed to the business’s success and decried his son’s “unproven insinuations.”
Wu, in her first public comments on the matter, told The Wall Street Journal in an email this month that her relationship to the chairman was “purely professional.” She said the elder Kwek had “asked for and considered my feedback on business ideas,” adding that she had “had no role in the decision-making process” at CDL. She said the dispute was between board members and “has nothing to do with me, although some parties have used my name to stoke the flames.”
Weeks after the clash, the sides agreed to a truce. The public warring had done no good for a company dealing with high debt and a lacklustre share price.
In March, the elder Kwek announced Wu’s resignation as an adviser at CDL’s hotel subsidiary and dropped his lawsuit. His son remains CEO, backed by additional allies on the board and a company resolution declaring that Wu has no power to influence or direct management and staff at CDL and its hotel business.
But Wu is still in contact with one person at CDL: the 84-year-old chairman. People at the company say the elder Kwek and Wu, who turns 66 this month, have recently been seen meeting at CDL-owned properties. It means, the people say, that the saga is far from over.
Just north of the equator, six million people swelter in a city-state about a quarter of Rhode Island’s size. A disproportionate many are millionaires, and some of Singapore’s richest residents are members of family businesses that predate the nation’s 60 years of independence.
As Singapore transformed from a colonial outpost into a hub of prosperity, the Kwek clan was there to help build it every step of the way.
Kwek Leng Beng’s father, Kwek Hong Png, started a construction-materials store in 1941, when Singapore was a British colony. Kwek Leng Beng joined the business in 1963 and was given stern training by his father, as he and Cecilia recounted in an authorised biography, “Strictly Business.”
When the couple were dating, Kwek Leng Beng’s father imposed a curfew. “The old man wanted him to be in bed by 9 p.m.,” Cecilia said in the biography.
Kwek Leng Beng and Cecilia, both London-trained lawyers, wed in 1970. They spent much of the next few years in Singapore in the lobby of the company’s first hotel, where she’d drink hot chocolate while he quizzed staff about occupancy rates and mingled with guests for feedback, the biography said.
By the 1990s, Kwek was in charge of a flourishing family business that would eventually expand to more than 150 hotels worldwide, including Millennium hotels in New York and London. It controlled so much real estate in Singapore at one point that he was dubbed “Kwek Land Bank.”
As part of a venture with a Saudi prince, CDL bought New York City’s Plaza Hotel, the iconic establishment next to Central Park that’s played host to royalty, presidents and the fictional Kevin McCallister in the 1992 movie “Home Alone 2.” They paid $325 million to buy it from Trump in 1995, and then sold it nine years later for $675 million. In the mid-2000s, Kwek advised Las Vegas casino magnate Sheldon Adelson on building the Marina Bay Sands casino resort in Singapore. Today, it is a symbol of the island nation’s skyline.
As the years went by, an adviser by Kwek’s side became impossible for insiders to ignore. Catherine Wu, who holds a doctorate in music from New York University, was in her early 30s when she met Kwek in 1992 at a dinner party. She was well-known in Taiwan as a TV host and pianist, having released albums under the name Ingrid Wu with tracks such as “His Lover” and “I’ll Decide Before Dawn Whether I Love You.”
At the dinner, Kwek quizzed Wu about politics, economics and music “to see if my mind was flexible and if my answers were consistent,” Wu told a Singaporean newspaper last year. “Fortunately, I answered articulately.”

Wu decided to move to Singapore that same year, she told the newspaper, saying she wanted to escape attention by relocating to a place where she wasn’t well-known, and that the city-state’s East-meets-West vibes suited her. In her email to the Journal, Wu described music as her former career and said she had spent 30 years in business amassing professional achievements.
Kwek invited her to hotel-management meetings and events. “The chairman would scold me from time to time, but I wouldn’t take it to heart,” Wu said in the newspaper interview. “If a successful person is willing to put in the thought and energy to scold you, it means you are teachable.”
Paid not by the company but by Kwek himself, Wu acted as the chairman’s “eyes and ears” and often accompanied him to visit properties around the world, according to a 2018 U.K. labor tribunal ruling. The tribunal was investigating a dispute involving a former employee who accused a CDL subsidiary of unfair dismissal and other wrongdoing, a case the tribunal dismissed.
Some executives and employees—including people who later left the company—bristled at Wu’s conduct, filing complaints against her both internally and to a Singapore government-backed agency, according to people familiar with the matter. These complaints included allegations that Wu berated staff, meddled in business matters beyond her remit and used the elder Kwek’s name to rubber-stamp her decisions, the people said.
Sometimes, executives believed that business decisions they thought had been approved by the chairman were later overruled by Wu. In one instance cited in the complaints, the people said, Wu got the company to halt planned renovations to a hotel in London near the Harrods luxury department store, even though management believed the project would boost revenue and had spent years preparing for it.
Many employees came to believe that Wu was sometimes using one of the elder Kwek’s corporate email accounts to send instructions in his name, people close to CDL said. They said these employees learned to recognise what they believed to be Wu’s imprint on such emails—a more formal and detailed writing style, compared with the elder Kwek’s curt approach, and the signature “Sent from my iPad,” which was notable because the chairman wasn’t known to use an iPad. Kwek declined to comment, while Wu didn’t respond to requests for comment about this matter.
According to the people, some executives expressed unease when one of Wu’s six brothers, a former journalist for a Taiwanese television network, became general manager of the Biltmore Los Angeles in 2018. He had little experience in the hospitality industry, apart from a short stint as a business-development executive in CDL’s hotel subsidiary.
During the brother’s stint as general manager, he, the hotel and a company affiliated with CDL’s hotel subsidiary faced lawsuits from former Biltmore employees over allegations that included discrimination, harassment and wrongful termination, according to court papers. These cases have generally been settled out of court, according to court documents and people close to CDL, and the company didn’t make any public admission of wrongdoing. The brother has stepped aside as general manager and remains an owner’s representative—a supervisory role that oversees the hotel’s operations and liaises between its owner and management.
The brother didn’t respond to requests for comment.
Senior executives tried for years to persuade Sherman Kwek, the designated successor to the elder Kwek, to directly address the tensions over Wu, say insiders.
Sherman Kwek didn’t see much of his father as a child, as he recounted in his dad’s biography. After studying business at Boston University, he worked in venture capital and investment banking in New York before his father brought him to the family business.
Sherman Kwek had his own issues to deal with. After becoming CDL’s CEO, he had spearheaded a 2019 investment in a Chinese developer that went sour and led to a $1.4 billion write-down. “I wanted to hide my face in the sand” and came close to resigning, he recounted in a speech last year. “I went from hero to zero overnight.”
The younger Kwek retained his father’s support then and went on to strike profitable deals divesting some commercial properties, but he still faced scepticism from investors.
Sherman Kwek and his allies thought they had eased Wu out of the picture when she resigned as a director of CDL’s hotel subsidiary in January 2024, people close to the company say. But in August that year, Wu rejoined the subsidiary as an unpaid board adviser and the Singaporean newspaper published its interview with a headline that called her the elder Kwek’s “grand chamberlain.”
Wu’s return stunned some senior CDL figures and board members, who had to try again to remove her from the business, people close to the company say. They first appealed to the elder Kwek to act, and then—after seeing no results—initiated a move in late January to add new independent directors to the CDL board, the people say.
These efforts eventually led to the public feuding, which drew breathless coverage from local media that documented the boardroom spat blow-by-blow.
Following the truce earlier this year, after which Sherman Kwek continued as chief executive and his father as chairman, Wu now has no official title at the company.
Sherman Kwek remains in the hot seat, facing market pressure to execute plans to pare back CDL’s debt and lift its share price, which still languishes below prepandemic levels.

Watching over him is his father, who remains a revered figure at CDL overseeing a family fortune that Forbes estimated last year to be worth $11.5 billion. The elder Kwek has maintained his contacts with Wu, whose protégés still hold positions in the hotel business, according to people close to CDL. One of these people says the company is looking into past complaints against Wu. This week, CDL said a long-serving board member, who sided with the chairman during the feud, will retire from the board at the end of July.
A CDL spokesman said Kwek Leng Beng, Sherman Kwek and the company declined to comment.
Both father and son continue to go into CDL’s headquarters at Republic Plaza, a soaring 66-story skyscraper in Singapore’s business district.
At a public space there, a holographic painting that Sherman Kwek presented to the elder Kwek at the 2023 gala—depicting either the grandfather Kwek, the father or the son depending on the viewing angle—remains on display. Next to it stands a piece of Chinese calligraphy penned by one of Wu’s brothers, which says, “Three generations of blood and sweat, six decades of honour and glory.”

OpenAI has shelved the planned launch of GPT-6.1 Astra after internal tests raised concerns about deception and agents acting beyond user authorization, according to The Wall Street Journal. The company says it will investigate the issues and strengthen safety measures before releasing future models.
OpenAI says it is scrapping the release of its next-generation AI model over safety concerns that researchers raised during internal testing, in one of the clearest signs so far that agent misbehavior could stymie the industry’s rapid progression.
The move follows a summer punctuated by reports of artificial-intelligence systems industrywide going rogue, and marks a rare case of a major AI developer ditching a new release because of safety concerns.
The company had planned to launch the model, known as GPT-6.1 Astra, in the coming days or weeks, aiming for an October debut. The model was more capable than the company’s previous models in completing challenging tasks from end-to-end without human assistance, as well as writing.
The company instead will focus on improving the safety of future models, which it expects to be even more capable.
Saachi Jain, OpenAI’s head of safety systems, said in an interview that GPT-6.1 Astra regressed in two areas. Compared with its predecessor, GPT-6 Astra, the model performed poorly on tests measuring alignment, or how well the model adheres to what humans would like it to do. Specifically, GPT-6.1 Astra showed higher levels of deception: It wasn’t always honest about telling users of the actions it did or didn’t take.
Another issue was what OpenAI calls “scope authorization,” meaning that GPT-6.1 Astra would push ahead on a task without asking the user for permission, and would at times reach for external tools and services even if it might be unsafe.
“For anything regarding safety and alignment, there’s a trade off,” Jain said. “You really do need to find what’s the right line between staying within scope, but also avoiding laziness in terms of how the model actually pursues tasks even when it hits friction.”
While GPT-6.1 Astra improved in areas such as “model laziness,” Jain said it didn’t quite meet OpenAI’s bar for safety and alignment, so the company decided not to launch the model publicly.
The announcement comes one day ahead of OpenAI’s annual developer conference in San Francisco. In the past, OpenAI has used the conference as an opportunity to launch new models and services that reduce costs for software developers—a segment the ChatGPT-maker competes with rival AI company Anthropic to win over.
In recent weeks, OpenAI and Anthropic have called on industry partners to slow down the development of cutting-edge AI models and invest in safety standards, noting they will temper the pace of their own internal AI progress.
OpenAI says it is working to investigate a range of agent security incidents that it has discovered in recent months, and address the safety issues underneath them. As part of the work, the company has implemented a new monitoring system to catch AI-agent misbehavior more quickly, and started requiring engineers to use stronger security guardrails for testing its AI systems.
Earlier this summer hundreds of OpenAI’s internal agents, which were tasked with completing a cybersecurity test, ended up hacking into the AI company Hugging Face. Since then, high-profile organizations such as the Australian government and United Nations discovered that OpenAI’s agents used similar, but less extensive, techniques to gain access to their websites.
Many of the publicly known agent-security incidents involved OpenAI’s internal AI models that were never slated for public release.
Last week, OpenAI said it paused training on its most capable AI models after an AI agent slipped through a gap in the company’s internet restrictions to query a public chatbot. The company said its new monitoring systems flagged the incident within 15 minutes, and training on these models remains paused.
GPT-6.1 Astra isn’t one of those models, but a different case, the company said.
“We want to make sure our model development is safe no matter whether that’s in the company, or when we ship it to users,” Jain said. “But when we ship it to users, we have an extremely high bar in terms of safety and alignment.”
While the company decided not to ship GPT-6.1 Astra, it hopes to use the same base model to do additional reinforcement learning runs, and create future generations of its GPT-6 models.
OpenAI plans to conduct several deep dives to identify the root cause of the problems identified in GPT-6.1 Astra, Jain said. The work includes ensuring that OpenAI’s reinforcement learning environments are rewarding the right type of behavior, Jain added, though she noted the company would investigate all stages of model development.
AI companies have begun to draw scrutiny from policymakers and public officials, who are paying attention to the rapid development of the technology. Later this week, a Senate subcommittee is holding a hearing with third party AI researchers titled, “Rogue AI: Securing the Homeland Against AI Agent Attacks.”
Florida Attorney General James Uthmeier, a Republican, sued OpenAI in June, claiming that the company and Chief Executive Sam Altman knowingly released an unsafe product and ignored warnings that it could harm users.
In a motion for temporary injunction filed Monday, Uthmeier sought to prevent OpenAI from developing new AI models without third-party approved safeguards, stop ChatGPT from soliciting user engagement and limit the company’s ability to advertise ChatGPT as safe.
Tech companies claim they “cannot stop barreling forward with their potentially civilization-ending endeavors unless they are forced to do so by the government,” Uthmeier said in the filing. “The Florida Attorney General is answering your cry for help.”
An OpenAI spokeswoman said that people want to know AI is being developed safely, “and that starts with what companies like ours do ourselves.”
“Governments have an important role to play in setting robust safety standards for AI, and we’re committed to working with Florida and other states on advancing pragmatic AI policies that apply to the entire AI industry—not just one company,” she said.
