Hong Kong announced Wednesday that its postal service would no longer send packages to the United States, in response to the White House’s plan to charge tariffs on small, low-value parcels from the city.

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".
