Abstract: Since confidence is fading and anxiety is increasing in the US, America’s China policy has become more radical. In the short term,the US has the upper hand and China is in a relatively passive position. In the medium-and long-term,there will be more balance between them. This current strategic gambling between China and the US will be the major issue of international politics in the first half of the 21st century and the most prominent external challenge China faces. China needs to make strategic adjustments but the gamble may be worthwhile in correcting imbalance in the international order and in the co-evolution of the two countries. Full text available here.
