China unveiled on Friday retaliatory tariffs against about $75 billion worth of US goods, putting an additional 10 per cent on top of existing rates in the latest tit-for-tat exchange in a protracted dispute between the world’s top two economies.

The latest salvo from China comes after the US unveiled tariffs on an additional $300 billion worth of Chinese goods, including consumer electronics, scheduled to go into effect in two stages on September 1 and December 15.

China’s commerce ministry said in a statement it would impose additional tariffs of 5 per cent or 10 per cent on a total of 5,078 products originating from the US including agricultural products such as soybeans, crude oil and small aircraft. China is also reinstituting tariffs on cars and auto parts originating from the US.

“China’s decision to implement additional tariffs was forced by the US’s unilateralism and protectionism,” the Chinese ministry said in a statement, adding that its retaliatory tariffs would also take effect in two stages on September 1 and December 15.

US equity index futures fell on the news of China’s tariffs, pointing to opening losses on Wall Street.

White House trade adviser Peter Navarro told Fox Business News separately that trade negotiations with China would still go on behind closed doors.

The US trade representative’s office had no immediate comment on China’s tariffs announcement.
