China has vowed to continue pursuing tariff cuts and "win-win" cooperation with the United States, even as it imposed new restrictions on dozens of American firms. Speaking at a press conference on Thursday, Ministry of Commerce spokesman He Yadong confirmed that both sides will keep discussing reciprocal tariff reductions within the framework of a newly established trade board. He also said they would encourage cooperation in aircraft and agricultural products. This diplomatic overture follows a proposal by China's ambassador to the US, Xie Feng, to raise the limit on tariff-free goods from US$30 billion to US$300 billion.
