U.S., in nod to Tokyo, to send more ships to Japan, prods China

TOKYO (Reuters) - The United States moved on Sunday to reassure Tokyo over its mounting security concerns, saying it would send more missile defence ships to Japan following North Korean launches and use a high level trip to warn China against abusing its "great power."

Japan has watched with alarm in recent weeks as North Korea carried out a series of missile launches, including firing two medium-range missiles capable of hitting the U.S. ally.
