China vowed retaliation after the U.S. forced the closure of its Houston consulate, in one of the biggest threats to diplomatic ties between the countries in decades.

The U.S. government gave China three days to close its consulate in America’s fourth-most populous city in an “unprecedented escalation,” Foreign Ministry spokesman Wang Wenbin said Wednesday in Beijing. China planned to “react with firm countermeasures” if the Trump administration didn’t “revoke this erroneous decision,” Wang said.

The State Department said it ordered the consulate shut “to protect American intellectual property and Americans’ private information,” without giving more details. At least two Chinese citizens have been convicted of stealing energy industry trade secrets in Houston in recent years. The consulate is one of five China maintains in the U.S. along with its embassy in Washington.
