Hong Kong’s postal service will stop handling packages coming from or going to the United States amid an escalating trade war between the world’s two largest economies.

The move comes before President Trump’s planned imposition of new tariffs on small packages sent to the United States from Hong Kong and China.

One of China's top officials overseeing Hong Kong affairs, Xia Baolong, said on Tuesday that the United States' tariff war was "extremely shameless" and aims to "take away Hong Kong's life".
