US President Barack Obama’s just concluded Asia-Pacific trip is a strong signal that the US will re-energise its engagement with the region. It is important to remember that the US has been the dominant economic and military presence in the region since after World War II. With the collapse of the Soviet Union in 1991, the US sway was even more complete. China had started as an emerging economy in the 80s under Deng Xiaoping’s leadership after the Cultural Revolution and it depended on the US and its western allies for entry into their markets and into global trade forums like the World Trade Organisation (WTO). However, early in the present century, the US invaded Afghanistan and Iraq as part of its global war on terror, where it is still stuck, especially in Afghanistan. With the US distracted and increasingly mired in these two wars, China was able to raise its regional profile backed by impressive economic growth, and a steady rise of its military power. There was a growing feeling in the Asia-Pacific region that the US might not stick around for long, with China eventually replacing it as the dominant power. The global financial crisis in 2008 and 2009, which the US and Europe are still struggling with, tended to further increase this pessimism about the US. It is against this backdrop of China’s rise, and its impact on the region, that President Obama forcefully declared during a daylong visit to Australia that the US is an Asia-Pacific power and it is here to stay. As the US unwinds its military involvement in Afghanistan and Iraq, it is shifting its focus to Asia-Pacific where history will be made in this century. Obama said, “The US has been, and always will be a Pacific nation.” Therefore, “Let there be no doubt. In the Asia-Pacific in the 21st century, the US is all in.” The choice to make this declaration is important as both the US and Australia are further expanding their military and strategic alliance against the backdrop of a perceived threat from a rising China. The US-Australia military alliance under the ANZUS Treaty is being beefed up with the stationing of US marines in the country’s north, and with the use of naval and air facilities in the country’s west. Both the US and Australia deny that their expanded military relationship is directed against China, but there is very little doubt that China is seen as a likely threat. President Obama said in Canberra, “The US will play a larger and long-term role in shaping this region and its future, by upholding core principles [of human rights] and in close partnership with allies and friends.” In other words, China is forewarned that the US will not quietly fade away, and that it will not have an easy time with its neighbours unhappy with maritime disputes with China. These smaller countries are being assured that they can bank on the US to stand their ground. At the same time, the US will not let up on China on violation of human rights and the promotion of democracy. The assertion of China’s sovereignty over the South China Sea is likely to become a regional flashpoint at some point. China’s smaller neighbours, like the Philippines and Vietnam, have competing claims to the Spratly group of islands in the South China Sea that have caused some naval incidents blamed on China. The US and the Philippines are taking steps to boost their defence relationship. The US and Vietnam are also forging closer political and military ties, and there has even been talk of a former US military base (of the Vietnam War time) being revived. The US and Japan are already close military allies, with their alliance further beefed up in the last few years. China and Japan too have competing maritime claims in the East China Sea, leading to naval skirmishes not long ago. At the same time, the Korean Peninsula remains a live wire with North Korea unwilling to give up its nuclear capability. Though China is opposed to North Korea’s nuclear ambitions, it is not inclined to team up with the US and Japan, among others, to turn on Pyongyang. And Taiwan, of course, remains a live issue, with China claiming it as its own territory with the right to take military action if it were to declare independence. The US acknowledges China’s sovereignty over Taiwan, but is against the use of force by China to achieve it. At the same time, China’s sovereignty claim over the South China Sea is creating nervousness that it might interfere with open sea-lanes. All in all, Asia-Pacific is potentially a time bomb with all these claims and counter-claims. The South China Sea featured in the just-concluded East Asia Summit in Bali against China’s wishes, and is likely to become part of its agenda in subsequent summits. Beijing would prefer its discussion at a bilateral level between the concerned countries with competing claims. It regards the US as an external force that should not have anything to do with regional disputes. The US, of course, is determined to raise its Pacific profile as one that is and has always been a Pacific power. In other words, the US’s decision to make its Asia-Pacific policy a priority is likely to further complicate US-China relations. And Australia is right in the middle of it, being a willing, if not enthusiastic, partner of the US’s policy to contain China, if necessary. China’s People’s Daily warned Australia that it cannot play both sides of the coin hoping to maximise its economic gains from a booming trade relationship with China while siding with the US strategically. It said, “Australia surely cannot play China for a fool. It is impossible for China to remain detached, no matter what Australia does to undermine its security.” More importantly, though, Barack Obama’s revitalised Asia policy goes beyond Australia. In a way, it tells Beijing that the gloves are off and the US will make a determined stand in the Asia-Pacific region to stave off China’s push into the region and to push out the US. And for this, the US will foster new and reinforce old military and strategic ties with regional countries with maritime disputes with China or otherwise keen for a countervailing force to China’s rise. How this US-China competition for power will unfold is anybody’s guess. One thing is certain: the Pacific Ocean is unlikely to live up its pacific name with the new unfolding power game.
