LOS ANGELES — It was a perfect (if quiet) storm in the tense triangular relationship among Beijing, Tokyo and Washington, but with all the noise coming from North Africa and the Middle East, hardly anyone noticed three developments.

The first one involved China. President Barack Obama pulled Commerce Secretary Gary Locke, a quiet Chinese-American, out of his Cabinet and re-assigned him to Beijing to replace former Republican Utah Gov. John Huntsman, who is considering a run for the White House.

Huntsman's resignation as America's ambassador to Beijing is effective April 30. Locke, with his West Coast perspective on international issues, was a good quick substitute pick. It might even prove a net plus.
