Signs are getting stronger that United States President Barack Obama will turn down a proposed special duty against Chinese tire imports, said a Chinese business executive returning from a week-long trip to the US.

"More groups are lining up against the proposal," Shen Weijia, executive director of Giti Tire China, told China Daily.

The nine-member Chinese team, including tire makers, spent the week lobbying US authorities and attending a hearing held by the US trade representative.
