Security agents and curious onlookers descended on central Chengdu, as the leafy southwestern Chinese city suddenly became the centerpiece of the latest chapter in collapsing relations between Beijing and Washington. br br China’s decision Friday to close the American consulate in the Sichuan provincial capital -- in retaliation for a similar move by the U.S. three days earlier in Houston -- drew usually large groups of pedestrians onto the streets around the facility. Dozens of police and army personnel patrolled the street outside the building, checking IDs, searching phones and ordering passersby to delete photos and videos of the area. br br State broadcaster China Central Television began live-streaming footage of the consulate’s entrance. More than 20 million internet users were following the feed by Friday afternoon, in an odd echo of videos circulated earlier this week on social media showing Chinese consulate personnel in Houston burning what appeared to be reams of paper after learning of their looming expulsion. br br “It’s a shame,” said the owner of a nearby noodle shop popular with American diplomats, who went by the surname Ma. “They were always polite and spoke pretty good Chinese,” he said, adding that his street-side eatery got many Western customers because it serves less spicy versions of local cuisine. br br The Chengdu mission, which opened in 1985, covers Chongqing, Guizhou, Yunnan, as well as Sichuan. The consulate has also served as a key listening post to follow events in Tibet, where Communist Party efforts to suppress dissent have long been a focus of tensions between China and the West. Intel Corp., Dell Technologies Inc., and Procter & Gamble Co. are among American multinationals with a presence in Chengdu. br br Chinese Foreign Ministry spokesman Wang Wenbin told a regular news briefing Friday in Beijing that some consulate staff had “engaged in activities inconsistent with their capacity, interfered in China’s internal affairs and harmed China’s national security interests.” The U.S. State Department had similarly accused China of using the Houston consulate as a hub for spying and influence operations before taking the unprecedented step of closing it down. br br “It was a reasonable reaction,” said one Chengdu resident who lives near the embassy and asked not to be named. “It was the U.S. who first broke the peaceful relationship.” br br A total of roughly 700 diplomats are normally assigned to the U.S. embassy and five consulates in China br br In 2012, former Chongqing police chief Wang Lijun sought refuge in the Chengdu consulate with evidence linking the family of his then boss, former Chongqing party secretary Bo Xilai, to the death of a British businessman. The episode exposed a scandal that would see Bo ousted and his wife convicted of murder, leading Xi to launch a nationwide anti-corruption campaign. br br Local residents said that the police presence increased markedly overnight.
