The United States and China have held ministerial-level trade talks. Items on the agenda included China's purchases of farm goods and industrial subsidies.
US Trade Representative Katherine Tai held a virtual meeting with Chinese Vice Premier Liu He.
The US government said Tai asked China to steadily implement the "Phase 1" deal struck in January last year with the then Trump administration. China promised to buy US farm goods under the deal.
Tai also reportedly conveyed concerns about structural issues, including what the US calls China's excessive state subsidies.
The Chinese government said it asked the US to lift sanctions and abolish additional tariffs of up to 25 percent on Chinese imports.
The Chinese side also said it explained the country's industrial policy. The move is seen as an effort to counter US criticism of Beijing's industrial subsidies.
Earlier this month, the US government announced a new policy on trade negotiations with China that places greater emphasis on dialogue. The US regards the latest call as the start of full-scale trade negotiations under the administration of President Joe Biden.
The two countries have agreed in principle that Biden and Chinese President Xi Jinping will hold talks online by the end of the year.
