Democratic Rep. Adam Smith said the committee would look at how the U.S. can guarantee its alliance commitments with nations like South Korea and Japan, while building on its many other relationships in the region.
"One of the keys to making this work is partner capacity," he said, citing as an example U.S. counterinsurgency support for Philippine forces fighting Islamic rebels. "What other options are out there to build capacity in forces so it doesn't all fall on us?"
But Smith also advocated cooperation with China, which views the U.S. pivot as an attempt to encircle and crimp its emerging power. Smith said China should be viewed as a partner that could work with the U.S. on issues including North Korea and the transition in Afghanistan.
Republican committee chairman Howard McKeon sounded less accommodating.
He supported a more active role for Japan's military in response to assertive behavior by China. Japan has the region's second strongest military after China but it remains constrained by its pacifist constitution.
"It's incumbent upon us to do all we can to build up and strengthen our partners so they can bring more to the table when they are needed," McKeon said.
That risks tension not just with China but South Korea. Both those nations nurse bitter memories of Japan's colonialist expansion in the first half of the 20th century and wartime atrocities.
Democratic Rep. Colleen Hanabusa said the U.S. needs to be more mindful of historical conflicts between its allies like South Korea and Japan, and recognize that Washington won't be able to solve them.
"They have got to, on their own, decide that this is either a conflict they can park on the side for a little or resolve. We are not going to be able to resolve history," she said.
