- Trump and economic adviser Gary Cohn said China forced U.S. companies to transfer their intellectual property to China as a cost of doing business there.
- U.S. businesses say they lose hundreds of billions of dollars in technology and millions of jobs to Chinese firms which have stolen ideas and software.
- Trump did not specify what he meant by a "fine" against China.
President Donald Trump said on Wednesday the United States was considering a big "fine" as part of a probe into China's alleged theft of intellectual property, the clearest indication yet that his administration will take retaliatory trade action against China.
The United States has started a trade investigation into the issue, and Cohn said the United States Trade Representative would be making recommendations about it soon.
"We have a very big intellectual property potential fine going, which is going to come out soon," Trump said in the interview.
While Trump did not specify what he meant by a "fine" against China, the 1974 trade law that authorized an investigation into China's alleged theft of U.S. intellectual property allows him to impose retaliatory tariffs on Chinese goods or other trade sanctions until China changes its policies.
Trump said the damages could be high, without elaborating on how the numbers were reached or how the costs would be imposed.
"We're talking about big damages. We're talking about numbers that you haven't even thought about," Trump said.
U.S. businesses say they lose hundreds of billions of dollars in technology and millions of jobs to Chinese firms which have stolen ideas and software or forced them to turn over intellectual property as part of the price of doing business in China.
The president said he wanted the United States to have a good relationship with China, but Beijing needed to treat the United States fairly.
Trump said he would be announcing some kind of action against China over trade and said he would discuss the issue during his State of the Union address on Jan. 30.
Asked about the potential for a trade war depending on potential U.S. action over steel, aluminum and solar panels, Trump said he hoped a trade war would not ensue.
"I don't think so, I hope not. But if there is, there is," he said.
The president also said he and Chinese President Xi Jinping had not discussed China's plans with regard to purchases of U.S. Treasury bonds.
Bloomberg reported earlier this month that Chinese officials reviewing the country's foreign exchange holdings had recommended slowing or halting purchases of U.S. Treasury bonds.
Trump said he was not concerned such a move would hurt the U.S. economy.
"We never talked about it. They have to do what they do," he said.
