U.S. plans to shake up international postal rates next month

The issue is a familiar one: package post costs from China to North America are too cheap.
Under the current postal system, countries receive a fixed terminal-delivery fee per item under 2 kg, with the net amount paid from the post office of the sending country to the post office of the receiving country as a lump sum each period based on volume and balance in each direction in that period. But "developing" countries pay a special lower rate than developed countries, and the "developing" country that stands out by a huge amount is of course China. That's why your package shipments from China are so cheap compared to shipments within Canada/U.S..
The U.S. says they will withdraw from the UPU unless they get to set their own terminal-delivery rates per country. Canada will likely be affected, both because our retail business associations will push for the same treatment of Chinese direct shipments, and because the U.S. will not want to see goods from China enter indirectly via Canada.
