US official says Chinese subsidies hurt US workers

Deputy US Trade Representative Demetrios Marantis on Thursday urged China to follow through on commitments it made when it joined the World Trade Organization a decade ago. He says rampant Chinese violations on copywrited material cost US companies billions of dollars a year.
Marantis says the United States is prepared to file enforcement actions in the WTO if necessary. He says the US "will not negotiate indefinitely where US rights are concerned." US-China trade tension comes as the Obama administration attempts to get Chinese help settling nuclear standoffs with North Korea and Iran and important environmental and economic initiatives.
