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".

The move comes in response to the US government's decision to end a customs exemption for low-value parcels from Hong Kong. This exemption, known as the "de minimis" rule, currently allows tax-free entry for shipments valued under $800. Starting May 2nd, these parcels will face a hefty 120% tariff.

Hong Kong's post office will stop shipping small parcels to the United States after Washington announced plans to charge tariffs on small-value parcels from the southern Chinese city, the government said Wednesday.
