(June 10): US Secretary of State Michael Pompeo criticized HSBC Holdings Plc for backing China’s move to impose national security legislation in Hong Kong, underscoring the increasing political pressures on multinationals dependent on the former British colony.

Pompeo accused the London-based banking giant in a statement Tuesday of assisting the Chinese Communist Party’s “coercive bully tactics” against the U.K. The criticism by the top U.S. diplomat comes after one of the largest shareholders in HSBC and Standard Chartered Plc expressed discomfort with the banks’ decision to support the legislation without knowing its provisions and how they will be used.

“The CCP’s browbeating of HSBC, in particular, should serve as a cautionary tale,” Pompeo said. “That show of fealty seems to have earned HSBC little respect in Beijing, which continues to use the bank’s business in China as political leverage against London.”

Pompeo added: “Free nations deal in true friendship and desire mutual prosperity, not political and corporate kowtows.”

Shares of HSBC fell as much as 1.5% Wednesday in Hong Kong, compared with a 0.1% gain in the benchmark Hang Seng Index as of 12:30 p.m.

The Chinese Ministry of Foreign Affairs in Beijing didn’t immediately respond to a request for comment. A Hong Kong-based spokeswoman for HSBC declined to comment. Representatives of Ping An Insurance Group Co. and Vanguard Group, two major HSBC investors, also declined to comment.

Political Risk

The statement shows how difficult it’s getting for companies to manage political risks amid the increasingly contentious relationship between the world’s two largest economies. HSBC and Standard Chartered are both headquartered in London, but make most of their profits in Asia. Hong Kong accounted for more than $12 billion of HSBC’s pretax profits last year.

Chinese President Xi Jinping’s government has become increasingly assertive in efforts to force foreign nations, companies and individuals to support its sovereignty over places like Hong Kong and Taiwan. Last year, the chief executive officer of Cathay Pacific Airways Ltd. resigned after China rebuked the Hong Kong-based carrier for its staff’s participation in a historic wave of pro-democracy protests.

Last month, China’s parliament announced and quickly approved a resolution that would impose legislation on Hong Kong criminalizing the harshest criticism against the government. Several of the city’s richest tycoons and their representatives have endorsed the move, even though pro-democracy advocates and a number of U.S. and U.K. officials have expressed concern that it would jeopardize the “high degree of autonomy” promised to Hong Kong before its return to Chinese rule in 1997.

The banks’ stance on China’s plans has already attracted political criticism in the U.K. Jacob Rees-Mogg, the governing Conservatives’ house leader, told lawmakers last week that HSBC may be more closely “aligned with the Chinese government than Her Majesty’s government.” Senior politicians from the opposition Labour Party said the banks’ positions were “completely at odds with the values framework in which financial institutions should be operating.”

Pompeo’s “kowtow” reference is loaded with historical significance, since China’s demands that British envoys prostrate themselves before the emperor were an early source of tension that helped precipitate trade-and-military clashes between the two powers in the 19th century. The U.K. took possession of Hong Kong in the Opium Wars, making it a base for British companies like HSBC, and beginning what China views as its “century of humiliation.”
