Compared with the progress Chinese Foreign Minister Wang Yi and US Secretary of State John Kerry seem to have achieved on sanctions against the Democratic People's Republic of Korea, finding common ground to resolve their differences over the South China Sea has proved more difficult.

Just as Wang has stressed, the responsibility for non-militarization of the South China Sea is not China's alone. The United States should lend an attentive ear to China's stance.

On Tuesday, at a hearing before the Senate Armed Services Committee, Admiral Harry Harris, head of the US Pacific Command, said China's deployment of missiles and new radars on its islands and reefs in the South China Sea and its building of airstrips are "changing the operational landscape" in the waters.

The media in the US also hyped up China sending Annihilates-11 fighters to the Xisha Islands. These voices may be a prelude to Washington escalating the flexing of its muscles in the South China Sea.

Yet as a non-regional country, it is irresponsible of the US to intervene in the South China Sea in disregard of the possibility that has emerged that China and the other parties to the disputes in the waters will be able to stabilize the situation rather than let it spiral out of control.

If those in the region were allowed to settle the disputes themselves, the South China Sea would be free from concerns and troubles within the foreseeable future.

It is the US' direct interventions in the South China Sea that are exacerbating tensions and adding uncertainty.

The US' provocative signals have seriously increased Chinese people's sense of urgency to strengthen the country's military capabilities. When US military vessels and warplanes intruded into the 12-nautical-mile territorial seas around China's islands and reefs, Chinese people have reasons to believe their country should not remain indifferent even if its military might is still inferior to that of the US.

On issues concerning national sovereignty, the Chinese military will follow the will of its people.
