US  President Donald Trump said on Sunday that China had agreed to "reduce and remove" tariffs on US cars below the 40 per cent level that Beijing is currently charging on American-made vehicles.

A day after he and Chinese President Xi Jinping called a 90-day cease-fire in their trade war to allow time for negotiations, Trump said on Twitter: "China has agreed to reduce and remove tariffs on cars coming into China from the US.

Currently the tariff is 40 per cent".

Telecom, tech, auto companies and shipping firms are among the biggest gainers in China and Hong Kong after the trade truce between Washington and Beijing.

Telecommunications:ZTE Corp. surges as much as 11 percent in Hong Kong to the highest intraday price since July 18. Any easing of tensions between the U.S. and China comes as a big relief to ZTE's investors after the U.S. government briefly banned the company's purchase of parts from American suppliers earlier this year.

If China cancels tariffs on high-end imported cars, that should benefit dealerships as the prices will be lower, said Angus Chan, Shanghai-based analyst with Bocom International Holdings Co.
