U.S. officials called on Monday for “concrete action” from China to make good on its commitment to purchase $200 billion in additional U.S. goods and services in 2020 and 2021 under the “Phase 1” trade deal signed by former President Donald Trump.

The officials said Washington was losing patience with Beijing, which had “not shown real signs” in recent months that it would close the gap in the two-year purchase commitments that expired at the end of 2021.

The comments come a day before the U.S. government is due to release full-year trade data that analysts expect to show a significant shortfall in China’s pledge to increase purchases of U.S. farm and manufactured goods, energy and services.

Through November, China had met only about 60% of the goal, according to trade data compiled by Peterson Institute for International Economics senior fellow Chad Bown.

China continued to engage with U.S. officials on the issue, but Washington was seeking “concrete action”, not “talks for the sake of talking,” the official added.

U.S. officials said they would continue to press China to show “serious intent” to reach an agreement on their purchase commitments, but conceded the framework of the deal offered them little leverage to enforce the purchase commitments.

Regardless of how the negotiations wind up, U.S. officials said they would continue to target the core problems of China’s state-led economy, while working to boost U.S. competitiveness by diversifying markets and working with allies and partners.

Deputy U.S. Trade Representative Sarah Bianchi told a trade conference on Tuesday that China had failed to meet its purchase commitments under the deal and the conversations between Washington and Beijing had been “very difficult.”

The agreement, signed by Trump in January 2020, defused a nearly three-year trade war between the world’s two largest economies, but left in place tariffs on hundreds of billions of dollars of imports on both sides of the Pacific.

Zhao Lijian, a spokesman for China’s foreign ministry, said on Monday that the United States should work with China to push foward economic and trade ties.

“For the specific problems which emerge in economic and trade relations between the two countries, both sides should appropriately solve them in the spirit of mutual respect, equality and consultation,” Zhao told a news conference.

China’s Ministry of Commerce did not respond to a faxed request for comment.
