- Officials say President Donald Trump will soon sign a memorandum, directing the trade representative to target China's trade practices
- The goal of the investigation would be to go after Chinese intellectual property theft
- Top Democrats are pressing the Republican president to be tough on Beijing
President Donald Trump is expected to make a speech and sign a memorandum at the White House on Friday that will target China's intellectual property and trade practices, senior White House officials told CNBC.
Three top Democratic senators, in a rare show of bipartisanship, on Wednesday urged the president to stand up to Beijing. Senate Democratic leader Chuck Schumer pressed the Republican president to skip the investigation and go straight to trade action against China.
Tensions between Washington and Beijing have escalated in recent months as Trump has pressed China to cut steel production to ease global oversupply and rein in North Korea's missile program.
The European Union, Japan, Germany and Canada have all expressed concern over China's behavior on intellectual property theft.
U.S. Trade Representative Robert Lighthizer would then initiate an investigation under the Trade Act of 1974's Section 301, which allows the president to unilaterally impose tariffs or other trade restrictions to protect U.S. industries, the sources said.
It is unclear whether such a probe would result in trade sanctions against China, which Beijing would almost certainly challenge before the World Trade Organization.
U.S. Section 301 investigations have not led to trade sanctions since the WTO was launched in 1995. In the 1980s, Section 301 tariffs were levied against Japanese motorcycles, steel and other products.
"This could merely be leverage for bilateral negotiations," James Bacchus, a former WTO chief judge and USTR official, said of a China intellectual property probe.
Some trade lawyers said that WTO does not have jurisdiction over investment rules such as China's requirements that foreign companies transfer technology to their joint venture partners, allowing sanctions to proceed outside the WTO's dispute settlement system.
But Bacchus argued the United States has an obligation to turn first to the Geneva-based institution to resolve trade disputes, adding: "There is an obligation in WTO to enforce intellectual property rights that is not fully explored."
Lighthizer and Trump's Commerce Secretary, Wilbur Ross, have complained the WTO is slow to resolve disputes and biased against the United States.
The threat comes at a time when Trump has become increasingly frustrated with the level of support from Beijing to pressure Pyongyang to give up its nuclear and missile program.
Trump has said in the past that China would get better treatment on trade with the United States if it acted more forcefully against Pyongyang. Beijing has said its influence on North Korea is limited.
China counters that trade between the two nations benefits both sides, and that Beijing is willing to improve trade ties.
A senior Chinese official said on Monday there was no link between North Korea's nuclear program and China-U.S. trade.
Wyden, the top Democrat on the Senate Finance Committee, wrote to Lighthizer urging action to stop China from pressuring U.S. tech companies into giving up intellectual property rights.
Wyden's state of Oregon is home to several companies that could make a case regarding intellectual property rights and China, including Nike Inc and FLIR Systems Inc.
