The move escalates the trade war between the world's two largest economies. Another source who is familiar with the situation confirmed the Bloomberg report to Reuters.
President Trump escalated his trade war with China Tuesday, identifying an additional $200 billion in Chinese products that he intends to hit with import tariffs.
President Donald Trump has threatened to tax as much as $550 billion in Chinese products - an amount that exceeds America's total imports from China a year ago.
China's retaliation to those measures was "without any worldwide legal basis or justification", Lighthizer said Tuesday.
Trump's implementation of tariffs against China as well as allies such as the European Union, Canada and Mexico have been met with denunciations both overseas and at home from trade-friendly lawmakers.
Tuesday's announcement included a 205-page public notice and list of the individual products that could be hit by the new 10-percent tariffs.
The White House has complained that China has used predatory practices in a relentless push to grant Chinese companies an unfair advantage in the industries of the future, including robotics, electric cars and biopharmaceuticals.
Up until now, only a few companies, including Harley-Davidson Inc. and Brown-Forman Corp., have publicly said the tariffs will affect their businesses, as most U.S. retailers and consumer brands were spared in the first round of tariffs on Chinese imports. China has vowed to retaliate dollar-for-dollar to any further US tariffs.
Chinese officials are expected to retaliate in other ways, hitting USA firms in China with unplanned inspections, delays in approving financial transactions and other administrative headaches. Since then, the president has said his administration could impose duties on virtually all Chinese imports into the US. High-level talks between the two countries starting in May failed to deliver a breakthrough to head off a trade war. But Mr Trump hasn't backed down, arguing that China's unfair trading practices are hurting American workers.
The U.S. Chamber of Commerce, which has supported Trump's tax cuts and efforts to reduce regulation of businesses, also criticized the administration's move.
