Washington ? A Dubai-owned company announced Wednesday it will sell all its U.S. port operations within four to six months to an American buyer, providing new details about its sales plans that were forced by congressional concerns over terrorism security.

Lawmakers who criticized the Bush administration for approving DP World’s earlier plans to operate in the United States said they were satisfied. Still, the House voted 377-38 Wednesday to formally express its opposition to DP World running any port terminals in America.

DP World, the world’s third-largest ports company, said that until the sale is finalized, its U.S. businesses will operate independently. The announcement was the first time it described its plans for the newly acquired U.S. operations as a “sale” to a single, unrelated American buyer and indicated it would retain no stake.
