China urges caution and opposes moves that increase tension.
The United States and its allies may boost their military presence in the Asia-Pacific region, citing Pyongyang’s nuclear test, analysts said.
The comments came as China engaged in a flurry of diplomacy on Wednesday to ease regional tension.
“More drills by the US and its allies are possible in a bid to show their firm opposition to the nuclear test and other measures by Pyongyang they call provocative,” said Wang Fan, an expert on Korean studies at the China Foreign Affairs University.
