WASHINGTON (AP) — President Barack Obama plans to announce Tuesday the creation of a new enforcement office to challenge what the White House calls unfair trade practices worldwide.

A White House official described the initiative on condition of anonymity because Obama had not yet signed the executive order establishing the Interagency Trade Enforcement Center. He planned to do so Tuesday.

The official says the office will expand the administration's ability to challenge unfair trading practices in China and elsewhere. The new office will coordinate enforcement activity across several U.S. government agencies.

Obama accuses China of subsidizing homegrown companies and allowing counterfeiting and intellectual piracy.

Obama's most recent budget proposal asks Congress for millions of dollars for the new enforcement center and more U.S. inspectors in China.
