WASHINGTON - U.S. President Joe Biden and his administration are breaking out onto Asia's diplomatic stage in a big way, beginning with the first-ever leaders' meeting of the "Quad" (the United States, Japan, Australia and India) last Friday and followed by back-to-back foreign and defense minister meetings ("two-plus-two") this week in Tokyo and Seoul featuring Secretary of State Antony Blinken and Secretary of Defense Lloyd Austin. Never have two-plus-twos been arranged so early in a new administration, and they were not held even once during the Trump administration with South Korea.
