General Motors Corp. wants a bigger piece of rapidly growing markets in the Asia-Pacific region and will strongly promote cooperation with its three Japanese partners, a top GM executive said Monday in Tokyo.

Richard Wagoner, chairman and chief executive officer of GM, said the combined share of GM, Isuzu Motors Ltd., Suzuki Motor Corp. and Fuji Heavy Industries Ltd. in the region has reached 17 percent.

"We are right forward to be higher than 17 percent," he told a joint news conference with the Japanese partners, two days before the Tokyo Motor Show opens to the media.
