WASHINGTON, Dec 15 (Reuters) - U.S. President Joe Biden on Wednesday nominated Caroline Kennedy to be U.S. ambassador to Australia and Olympic figure skater Michelle Kwan as ambassador to Belize, the White House said. Kennedy, 64, is the daughter of John Kennedy, the 35th president of the United States who was assassinated in 1963. She previously served as U.S. ambassador to Japan from 2013-2017 under former President Barack Obama. Kwan is the winner of two silver Olympic medals in figure skating. She has served as an adviser to the U.S. Department of State on women"s issues. Australia is a key ally to the United States and that relationship has strengthened in response to China"s growing power and increasingly assertive behavior in Asia and beyond. Kennedy"s experience in Japan should be helpful in Canberra given that Australia and Japan are both members of the so-called Quad grouping, which includes the United States and India, that has been expanding cooperationin the face of China"s rise. In September, the United States, Britain and Australia announced a security pact dubbed AUKUS that will help Australia acquire U.S. nuclear-powered submarines and expand its security reach in the IndoPacific region. Kennedy was the first female U.S. ambassador to Japan. She trained as an attorney and has co-authored books on civil liberties and edited anthologies of poetry.
