SYDNEY (Reuters) - Japan will join a major U.S.-Australian military exercise for the first time in a sign of growing security links between the three countries as tensions fester over China's island building in the South China Sea.

While only 40 Japanese officers and soldiers will take part in drills involving 30,000 U.S. and Australian troops in early July, experts said the move showed how Washington wanted to foster cooperation among its security allies in Asia.
