Chinese military analysts have questioned whether the United States will be able to bring plans for more ­bases in Asia to fruition. Beijing has already reacted ­angrily to moves to base intermediate-range missiles in the region, saying it “will not stand idly by” if it does so. Collin Koh of RSIS Singapore said Southeast Asian nations were expanding their defence cooperation with the US and other regional powers such as Australia because their military strength paled in ­comparison with China’s. But he said the US move may prompt domestic challenges.
