China's Ministry of Finance announced in a statement Wednesday that it's exempting 16 types of exported U.S. goods from import tariffs ahead of stalled trade talks resuming with the Trump administration. The exemption is effective Sept. 17 through Sept. 16, 2020.Why it matters: President Trump's trade war has led to bigger trade deficits with China, it's dented consumer sentiment, and the International Monetary Fund has said the prolonged tensions weighed down the global economy. A survey by the American Chamber of Commerce in Shanghai released Wednesday found 51% of the business lobby's responding members said U.S. and Chinese tariffs had hurt revenue, though the interrelated issue of China's economic weakening was a more pressing factor, the Wall Street Journal reports.What's happening: Goods to be exempted from China's tariffs include cancer drugs and some chemicals. Bloomberg notes that U.S. agricultural items such as soybeans and pork were not included on the list that would be exempted from the 25% tariffs.The Ministry of Finance issued 2 lists of items for exemption. Per CNBC, which translated the documents, tariffs already imposed on goods to be exempted on "List 1" will be refunded. Products on "List 2" were said to be non-refundable, according to CNBC.#China publishes tariffs exemption list for U.S. products. List goes into effect Sep 17 for one year.
