Trump’s Cooking Oil Threat to China Lands After Trade Already Slumped

U.S. President Donald Trump has turned his attention to China’s cooking oil trade, warning that Washington could cut off purchases as part of escalating trade tensions. But analysts note the move may have little real impact—because Chinese exports of used cooking oil to the U.S. were already in steep decline.

Used cooking oil, often repurposed for biofuel production, had once been a lucrative export. In 2024, shipments to the U.S. hit a record 1.27 million tons, valued at about $1.2 billion. But after Beijing scrapped tax relief on exports, sales plunged this year. By mid-2025, volumes had dropped to around 387,000 tons, down more than 40% from the previous year.

Trump framed the move as retaliation for China’s decision to halt purchases of U.S. soybeans, a far more valuable commodity worth over $12 billion annually. While the cooking oil dispute adds another flashpoint to the trade war, experts suggest it is largely symbolic compared to the broader agricultural and energy trade between the two nations.
