BEIJING - Vietnam has nearly doubled its military spending, Japan is requesting its biggest-ever defense budget and the Philippines is rushing to piece together a viable navy.
Several Asian nations are arming up, their wary eyes fixed squarely on one country: a resurgent China that is boldly asserting its territorial claims all along the East Asian coast.
The scramble to spend more defense dollars comes amid spats with China over contested reefs and waters. Other Asian countries such as India and South Korea are quickly modernizing their forces, although their disputes with Beijing have stayed largely at the diplomatic level.
Asian countries now account for about half of the world’s arms imports, with China leading the way by quadrupling its annual military budget over the past decade. The growth in military spending has largely kept pace with economic expansion, although it has been pulling ahead in China, Vietnam and several other countries this year.
China’s goal is to dislodge the U.S. as the dominant power in the Pacific, said Robert D. Kaplan, chief geopolitical analyst for the U.S.-based intelligence research firm Stratfor. Among the stakes are vital shipping lanes in the South China Sea and potentially lucrative pockets of oil and natural gas under East Asian waters.
“The Chinese bet is that it can increase its military capacity in the South and East China seas faster than Vietnam and the Philippines can do so,” Kaplan said. “If China is able to move freely and exercise more control of its adjacent seas, it will become a full-fledged naval power.”
China’s spending nearly equals the total defense budgets of all 24 other countries in East and South Asia.
Drawing the most attention is China’s submarine fleet, which is projected to match U.S. numbers by 2020, at 78 vessels each. Many of the Chinese submarines will be stationed at a giant underwater base on Hainan Island, which juts into the South China Sea.
China’s moves have spurred a submarine shopping spree across Asia.
This year, Vietnam received the third of six submarines it ordered from Russia plus maritime patrol aircraft capable of hunting down Chinese subs. Russia is the top military exporter to Asia, followed by the U.S. and then European countries such as the Netherlands.
Over the summer, Vietnamese and Chinese ships rammed each other repeatedly after China moved an oil rig into waters claimed by both countries. Vietnam’s military spending expanded by 83 percent over the past five years, making up 8 percent of government spending.
Similarly, Japan is replacing its entire fleet with more modern submarines, South Korea is adding bigger attack submarines and India plans to build six new subs.
Compared to Vietnam and Japan, the Philippines is lagging behind. After helplessly watching China build atop reefs in the Spratly Islands, which both countries claim, the Philippines welcomed U.S. troops back to its bases after a 20-year absence. And it plans to boost spending on maritime patrol aircraft, bombers and other hardware.
“The Philippines is doing a lot of work to invest in military modernization,” said Jon Grevatt, Asia-Pacific defense analyst at the research group IHS Jane’s. “For many years its economy has been growing and for many years it hasn’t been able to respond to these requirements.”
Even in South Asia, where China has taken a relatively hands-off approach, India has bought so many tanks and jet fighters that it has become the biggest arms importer in the world. India has also created a 100,000-person mountain corps near disputed stretches of its border with China.
Despite the focus on marquee hardware, much of the action so far has involved coast guard ships that can easily jockey for control of disputed islands and fishing waters.
In June, Japan agreed to donate six coast guard vessels to Vietnam, after pledging 10 to the Philippines last year. On its own, Vietnam has nearly doubled its coast guard fleet to 68 vessels over the past five years. And Japan has expanded its main coast guard fleet by 41 vessels, for a total of 389 ships.
Last month, Prime Minister Shinzo Abe’s government requested Japan’s biggest-ever military budget — equal to $48 billion — with outlays for P-1 surveillance aircraft, stealth fighters and other U.S.-built hardware.
In July, Abe’s Cabinet approved a reinterpretation of the Constitution allowing it to defend American and other foreign troops under attack. This month, Japan and India pledged to share defense technologies and hold joint military exercises.
“If China is being more bellicose, it’s because they see winds of opportunity,” said Bernard Loo Fook Weng, a military studies expert at the S. Rajaratnam School of International Studies in Singapore. “This may all step toward a more violent situation.”
