BEIJING Herren Nike Air Presto Zen Grau Gelb Marine Schweiz , Aug. 21 (Xinhua) -- China's Ministry of Commerce (MOC) said Monday the country will take "all appropriate measures" to defend its legal interests in response to a U.S. trade investigation that has aroused tension between the world's two largest economies.


Without specifying those measures, an MOC spokesperson said China will keep an eye on the investigation in a statement.


U.S. Trade Representative Robert Lighthizer Friday formally initiated an investigation into China's intellectual property (IP) practices under a rarely used trade law, despite worries about potential harm to China-U.S. trade ties.


Section 301, once heavily used in the 1980s and the early 1990s, allows the United States to unilaterally impose tariffs or other trade restrictions on foreign countries. But the country has rarely used the outdated trade tool since the World Trade Organization (WTO) came into being in 1995.
