Delivering a key policy speech to the Diet, Prime Minister Shinzo Abe said Thursday that no country should resort to the use of force to "change the status quo" regarding territorial disputes, in an apparent warning to China.

Abe didn't elaborate further, nor did he mention China by name.

In another part of the prime minister's annual policy speech, however, Abe urged China "not to conduct any dangerous acts" that could escalate the Senkaku dispute, referring to incidents in January when Chinese warships allegedly locked their weapon-targeting radar on Maritime Self-Defense Force units. Beijing has denied the allegations.
