A multilayered multipolar international order has been established. Seven major powers are divided into three categories，China being in the second category. States are strengthening and adjusting their security strategies in a bid to gain a more favorable power status. To safeguard its hegemonic leadership，the U.S. attaches equal importance to non-traditional and traditional security challenges and is shifting its geo-strategic focus to the Asia-Pacific region and its regional security focus to cyberspace and climate change. Russia is implementing a new security strategy，posing a major challenge for NATO and the U.S.，and Russian foreign policy and geostrategy are far more aggressive than before. In Japan，the Abe administration continues to adopt an unwavering right-leaning policy，and shore up its alliance with the U.S. against China，aiming to become a political and military superpower. The contestation between the West and the emerging powers is becoming increasingly intense. Enmity between Washington and Moscow has intensified. The alliance forged between the United States and Europe to corner Russia is not as strong as they wish it could be. The power struggle between China and the United States is becoming more intense as the United States joins hands with Japan in an attempt to curb the rising of China. Western powers huddle up together closer while China and Russia join hands to exert influence on relations between emerging powers. Despite its rising global might，China is faced with complex challenges.
