The United States ordered China to close its consulate in Houston, escalating tensions between the world's largest economies as President Donald Trump ramps up pressure against China ahead of the November election. Beijing denounced the order Wednesday as "outrageous" and said it would draw a firm response if not reversed. The physical closure of the consulate, one of China's six missions in the United States, marked a dramatic step in increasingly contentious relations that have been strained not only by the conronavirus pandemic but disputes over trade, human rights, Hong Kong and Chinese assertiveness in the South China Sea. Previous Trump administration measures against Chinese officials, students and researchers have included travel bans, registration requirements and other steps intended to reduce the country's footprint in the United States. The administration has also announced its outright rejection of virtually all Chinese maritime claims in the South China Sea. These actions have come as Trump has sought to blame China for the coronavirus outbreak in the U.S., where cases have soared, threatening his prospects for reelection. The State Department said it ordered the consulate closed within 72 hours after alleging that Chinese agents have tried to steal data from facilities in Texas, including the Texas A&M medical system statewide and The University of Texas MD Anderson Cancer Center in Houston. There were indications consulate staff were preparing to leave: Papers were being burned on the consulate grounds late Tuesday night a common practice when a diplomatic post is being shuttered on short notice. "It has been long discussed and asserted that the office here in Houston was engaged in inappropriate forms of information gathering and influence operations," said Hans Stockton, a professor of international studies at St. Thomas University-Houston. "It's not necessarily surprising, one would expect foreign governments to be very aggressive in collecting information that would be helpful to their own national interest," said Stockton.
