China's Defense Ministry says it will respect freedom of passage in the South China Sea but is calling on the US to be sensitive to China's needs.
The Ministry is also urging calm and constraint when it comes to dealing with the Korean peninsula.
A Defense Ministry official says China has "indisputable sovereignty" over islands in the South China Sea and the surrounding waters.
He says China will push for the resolution of differences regarding the South China Sea with the individual countries involved through dialogue and negotiations.
Senior Colonel Geng Yansheng, Defense Ministry Spokesman, said, "We oppose the internationalization of the South China Sea issue, and at the same time will, in accordance with the demands of international law, respect the freedom of passage for ships or aircraft from relevant countries."
He says China is deeply concerned about the recent joint military exercise between South Korea and the US.
Senior Colonel Geng Yansheng, Defense Ministry Spokesman, said, "We urge relevant countries to maintain calm and restraint and do not carry out activities that would aggravate the situation."
He also commented on China's military exercises.
He denied a report saying hundreds of aircraft flew over China's eastern coastal city of Qingdao on July 26th.
He says China is becoming increasingly transparent in its military exercises, and asked media to cover the country's exercises in an accurate manner.
The spokesman also said the People's Liberation Army hopes to enhance cooperation with their counterparts in other countries to ensure effective and coordinated relief work in cases of natural disasters.
