A rapid buildup of nuclear weapons by China and its apparent determination to restrict United States forces' access to the western Pacific is threatening to transform the balance of power in East Asia.
Tensions in the region were demonstrated at a meeting of the foreign ministers of Japan, China and and South Korea in Gyeongju in South Korea on May 15.
Though the main topic of the meeting was the sinking of the South Korean corvette Cheonan, a testy exchange between the foreign ministers of Japan and China showed strategic concerns simmering below the surface.
Japanese Foreign Minister Katsuya Okada told the Chinese representative, "Among the countries that possess nuclear weapons, only China is increasing its nuclear weapons."
This angered Chinese Foreign Minister Yang Jiechi. Without turning on his microphone, he said, "There is nothing to justify being told such a thing by Japan, which is protected by the U.S. nuclear umbrella." He then started to leave his seat.
Wednesday will mark the 50th anniversary of the beginning of the revised Japan-U.S. Security Treaty, but China's increasing military assertiveness is raising questions about the continuing efficacy of Japan's defense strategy.
China is estimated to have about 400 nuclear warheads, a fraction of the more than 5,000 warheads held by the United States. China has declared that it will not use its nuclear weapons for preemptive strikes.
"We continue to maintain the minimum-level nuclear capabilities that are required for the safety of our country," said Ma Zhaoxu, director-general of the Information Department of the Chinese Foreign Ministry.
But, despite the soothing words, China is quietly transforming its long range nuclear capabilities. New missiles include the Dong Feng 31A, an intercontinental ballistic missile with a range of 14,000 kilometers.
The shorter range Dong Feng 21C missile has Japan well within its range and a new type of anti-ship ballistic missile can pursue vessels at supersonic speeds.
China is also constructing underground bases for nuclear missiles in mountainous areas in Henan and Shanxi provinces, aimed at protecting them from preemptive strikes.
The missile development is a vital part of an emerging "anti-access" theme in Chinese military strategy aimed at preventing U.S. aircraft carriers from advancing into sea areas near China in the case of a stand-off between the two countries over Taiwan.
"If we place U.S. aircraft carriers and U.S. bases in Japan within the range of our missiles, the U.S. fleets will not be able to enter the western Pacific freely. As a result, we will make the Japan-U.S. Security Treaty ineffective," said a source close to China's military.
Submarines are another important pillar of the anti-access strategy. In recent years, China has developed state-of-the-art Song-class and Kilo-class submarines with quiet propulsion technologies that make them difficult to detect.
The new technology has allowed much more aggressive deployment. The Chinese military has told U.S. military officials that two Chinese submarines are permanently stationed in waters near the United States.
In October 2006, a Chinese Song-class submarine surfaced about eight kilometers from the U.S. aircraft carrier Kitty Hawk near Okinawa Prefecture.
The U.S. ship had been unaware of the Chinese submarine's presence and was within the range of the Chinese submarine's torpedoes.
The Chinese navy flexed its muscles again in April this year, when a fleet of 10 vessels, including two Kilo-class submarines, passed between the main Okinawa island and Miyakojima island.
A Chinese helicopter came within about 90 meters of a Japanese Maritime Self-Defense Force's escort warship during the incident.
The Chinese Defense Minister Liang Guanglie told a delegation of Japanese Self-Defense Forces' officers in Beijing on June 11 that the passage was part of a training exercise and was not a violation of international law.
"Though the Self-Defense Forces' reconnaissance planes frequently come to (air space over) the Yellow Sea (between China and the Korean Peninsula), the Chinese military forces are not obstructing them. We hope that the Japanese side do not watch us too closely either," Liang said.
However, a military source in Beijing said the maneuver had a more profound motivation: "The passage was made to demonstrate to Japan and the United States the improvement in China's anti-access capabilities in the East China Sea."
According to the Japanese Defense Ministry, Chinese destroyers have been detected near Miyakojima island and Okinotorishima island five times since 2008.
One of the Japanese officers present at the meeting with Liang said, "We felt that China has established superiority and that Chinese naval power is already greater than Japan's."
Chinese military officers say that China's military buildup is focused on Taiwan.
The primary target of its increasing strategic assertiveness is not Japan but the United States, which has been selling weapons to Taiwan. But China recognizes that accidental clashes with Japan in the East China Sea may be a side effect of the policy.
When Chinese Premier Wen Jiabao met with then Japanese Prime Minister Yukio Hatoyama in Japan in late May, he proposed re-establishing a hotline between the leaders. The hotline had not yet been set up and the Chinese side appeared to have gone cold on the idea.
At the same meeting, the two leaders agreed to improve other crisis management mechanisms to deal with confrontations at sea.
Meanwhile, the sinking of the South Korean corvette Cheonan in late March raised questions about Japanese and South Korean security cooperation. The Japanese government was slow in responding to the incident and did not ask to participate in the investigation into the causes of the incident.
The Cheonan's sinking, which the international investigation blamed on Pyongyang, was a stark reminder of the military power of North Korea. The reclusive country has up to 180,000 special military troops, weapons of mass-destruction, ballistic missiles, and submarine capabilities, all of which threaten both South Korea and Japan's security.
Japanese officials are pushing for greater cooperation with South Korea on security issues but the response from the South Korean side has often been unenthusiastic.
There is a strong resistance in South Korea to establishing a military alliance with Japan because of the friction resulting from Japan's occupation of the Korean Peninsula. There is also concern about China's opposition to such an alliance.
Nevertheless, there is an understanding among some in the South Korean military of the two country's common interests.
A South Korean officer said, "An (military) alliance (between South Korea and Japan) may be impossible. But both countries always need to maintain high-level friendly relations."
