WASHINGTON: A bipartisan group of US lawmakers complained to the Trump administration on Monday that its response to rights abuses against China’s Muslim minority was inadequate months after saying it was looking into imposing sanctions. “This issue is bigger than just China. It is about demonstrating to strongmen globally that the world will hold them accountable for their actions,” the lawmakers wrote in a letter to US Secretary of State Mike Pompeo. The group is led by Representative Eliot Engel, Democratic chairman of the House Committee on Foreign Affairs and includes Republican ranking member Representative Ted Yoho. The letter said Pompeo had written to the committee on Sept. 28 saying his department was looking into the request for sanctions on those responsible for abuses and for controls on exports of technology that facilitates mass detentions and surveillance of ethnic minorities in western China’s Xinjiang region. “More than four months later, it appears that the Administration has taken no meaningful action ... and we write today with a renewed sense of urgency on this serious matter,” said the letter, also signed by Representative Brad Sherman, Democratic chairman of the subcommittee on Asia and the Pacific and Representative Chris Smith, Republican ranking member of the subcommittee on human rights. China denies the allegations. The State Department did not immediately respond to a request for comment. The US ambassador for International Religious Freedom, Sam Brownback, told reporters the issue was “being discussed thoroughly within the administration,” but he had no new steps to announce. Brownback spoke at a Capitol Hill event to mark the formation of the Coalition to Advance Religious Freedom in China, a multi-faith group of over a dozen religious and rights organizations established to campaign against persecution. US officials said last year the Trump administration was considering sanctions targeting companies and officials linked to China’s crackdown on minority Muslims, including Xinjiang Party Secretary Chen Quanguo, a member of the Chinese leadership’s powerful politburo. But no action has been forthcoming, with the administration engaged in sensitive negotiations to resolve trade disputes between the countries. China denies allegations of abuses in Xinjiang and in a November interview with Reuters, its ambassador to the United States warned of retaliation if Washington were to impose sanctions on Chen. The US lawmakers said it was a particular concern that US firms might be contributing to the Xinjiang persecution given commercial ties to Chinese tech companies that had profited from a surge in security spending there. They called for written responses from Pompeo as to whether the US government monitored the use of US technology that could be used for surveillance or detention in Xinjiang and information on any US firms providing such technology. The letter highlighted a Jan. 31 Reuters report saying that Hong Kong-listed Frontier Services Group, co-founded by former US military services contractor Erik Prince, had signed a deal to build a training base in Xinjiang.
