President Obama departs for Asia Thursday, with Chinese economic relations at the top of his agenda. Obama—who will also address North Korea and Iran with Beijing—warned of "enormous strains" if the U.S. and China did not correct current economic imbalances. China, as well as South Korea, may push against the president's agenda, worried that the U.S. has hurt economic relations by insisting on industry tariffs and through White House ties to labor.
