Territorial disputes roil Asia: The Asia-Pacific region is anything but calm as China continues to flex muscle and agitate over its territorial claims in the East and South China seas.
In recent weeks, China has conducted naval drills at James Shoal, more than 1,000 miles from the Chinese mainland but just 50 miles from Malaysia, which claims sovereignty over it.
A Chinese marine surveillance plane intruded on Japanese air space near two islands in the East China Sea claimed by Japan and caused Japan to scramble jet aircraft. The incident coincided with ships of both countries shadowing each other off the Senkaku Islands.
"Despite our repeated warnings, Chinese government ships have entered our territorial waters for three days in a row," Japanese Chief Cabinet Secretary Osama Fujimura said. "It is extremely regrettable that, on top of that, an intrusion into our air space has been committed in this way."
China merely shrugged off the protest. The islands, it said, are Chinese territory.
The intrusions are a significant escalation in the dispute over the islands, analysts say. And an unintended incident could occur that could lead to use of arms.
