In its assessment of global trends and alternative realities, the report also said that Europe, Russia and Japan will continue to experience a relative decline in its global influence.
The report said:
But the study said that the United States, while weaker, will most likely remain “first among equals” among the other great powers in 2030 because of its “preeminence across a range of power dimensions and legacies of its leadership role”, as well as its “soft power” that attracts outsiders.
"Nevertheless, with the rapid rise of other countries, the 'unipolar moment' is over and Pax Americana – the era of American ascendancy in international politics that began in 1945 – is fast winding down," it said.
At the same time, the report warned of major uncertainty over China’s rise as a global superpower.
“If Beijing fails to transition to a more sustainable, innovation-based economic model, it will remain a top-tier player in Asia, but the influence surrounding what has been a remarkable ascendance will dissipate,” it said.
Speaking at a news briefing, Mathew Burrows, counsellor to the National Intelligence Council said:
If tensions keep rising in Asia, more nations will embrace US leadership and China "can be its own worst enemy," Burrows added.
