LONDON — Local officials in London overwhelmingly rejected plans for a massive, new Chinese Embassy on Thursday.

The decision over the long-planned project is a bitter setback for the Chinese government, which currently operates its embassy out of a townhouse in central London. It also comes as a once-promising "golden era" in relations between the two countries has deteriorated in recent years.

In turning down the Chinese government's plans, councilors in the London borough of Tower Hamlets cited the need to protect 14th century ruins inside the proposed embassy grounds as well as concerns about potential terrorist attacks, public protests and traffic jams. The 870,000-square-foot complex was to be housed inside the United Kingdom's old Royal Mint near the Tower of London and was to be the biggest embassy in the country.

But it's not just about protecting old ruins

"It was a big defeat for them tonight," said Peter Golds, a local council member, referring to the Chinese government. "I'm absolutely delighted. It's real people power."

While local officials focused on planning concerns, speakers at the hearing also raised political ones, including Chinese officials' behavior on British soil and their human rights record at home. They cited Chinese consular staff beating a pro-democracy protester inside consulate grounds in Manchester in October.

They also raised the Chinese government's incarceration of an estimated 1 million Uyghurs in detention camps in western China and its crackdown on the pro-democracy movement in Hong Kong.

Among the speakers was Simon Cheng, a Hong Kong activist who was detained by Chinese mainland authorities in 2019 while working for the British Consulate in Hong Kong and eventually fled to London.

"We should not compromise and grant an authoritarian state the power to upgrade their facilities to suppress dissenting thoughts in the U.K.," Cheng said after the decision.

Local councilor argues the decision was based on the merits

Councilor Shafi Ahmed insisted the council had made its decision based on the merits.

But in his area of Tower Hamlets, which has a large Muslim population, the community also sympathizes with the persecuted Uyghurs, a predominantly Muslim ethnic minority in China.

When asked about China's policies toward the Uyghurs, Ahmed said he felt "disheartened, broken."

The Chinese government, which spent more than $300 million to buy the empty property, did not have an immediate comment on the decision. At a ceremony celebrating the purchase in 2018, Liu Xiaoming, China's ambassador to London at the time, praised the acquisition as a milestone in Chinese-British relations.

"I hope our two countries will work together to write a new chapter for the China-U.K. 'golden era,'" Liu said.

Earlier this week, British Prime Minister Rishi Sunak declared that era was over.

The Chinese government can still appeal the rejection of its embassy plan to the British government.
