President Donald Trump plans to withdraw from a postal treaty that has allowed Chinese companies to ship small packages to the U.S. at a steeply discounted rate, the New York Times reported Wednesday. Under the Universal Postal Union treaty, China and other developing countries have since 1969 been assessed lower rates than wealthier nations. The Times says the decision to withdraw was made at the urging of Trump's trade adviser Peter Navarro. The National Association of Manufacturers said Trump deserved credit for his focus on eliminating what it called "the anti-U.S. manufacturer subsidy China receives from the U.S. Postal Service."
