Sens. Tom Carper and Chris Coons joined a May 16 letter signed by 32 senators calling on the Donald Trump administration to put American jobs and national security ahead of China.

The senators wrote the letter in response to Trump’s announcement that he has directed the Department of Commerce to look at easing penalties imposed on China-based company ZTE for violations that include selling sensitive U.S. technologies to Iran and North Korea in violation of U.S. sanctions laws.

“Offering to trade American sanctions enforcement to promote jobs in China is plainly a bad deal for American workers and for the security of all Americans,” the senators wrote. “American workers and companies confront rampant theft of U.S. intellectual property, agricultural policies that disadvantage American farmers, restrictions on market access for U.S. service providers and manufacturers, and mercantilist industrial policies that have cost U.S. workers their jobs. America’s policies toward China should put American workers, farmers and businesses first, not China’s.

“We urge you to focus on identifying effective strategies to reshape China’s policy approach in each of these areas, such as through enforceable commitments to eliminate forced technology transfer policies, market distorting subsidies, data localization policies and foreign investment restrictions, and ensuring nondiscriminatory treatment of U.S. firms in regulatory and other proceedings. Above all, we urge you to remain steadfast in enforcing America’s laws,” the senators wrote.
