In fact, China, as a major country, is conducting construction activities on some South China Sea islands at a pace and with a scale befitting its international responsibilities and obligations in such fields as maritime search and rescue, disaster prevention and mitigation, navigation safety and fishery services in the South China Sea.

Any claims that China's activities will undermine "the freedom of aviation, the freedom of navigation and the orderly process of trade and global commerce" are unfounded, because these activities, on the contrary, will facilitate joint response to challenges on the sea and provide more guarantees for the safety of navigation.

Third, on solving maritime disputes, China and countries of the Association of Southeast Asian Nations (ASEAN) have identified a "dual-track" approach on the South China Sea, which calls for solving disputes through negotiations and consultation directly between concerned parties, and asks China and ASEAN member states to work together to maintain peace and stability.

Last but not least, neither Japan -- though its Prime Minister Shinzo Abe has been actively raising the South China Sea issue at the G7 summit -- nor other G7 member countries are parties related to the issue.

It is advisable that Japan, which still owes sincere apologies to the victims of its wartime atrocities, shoulder responsibilities to maintain regional security and stability instead of backing ridiculous and unreasonable claims by some countries for South China Sea islands.

It is also advisable that Washington not let the South China Sea issue damage its relations with China -- one of the most important bilateral ties in the world.

Other Western countries, with their economies still influenced by the global downturn, should refrain from letting the South China Sea issue hinder their close trade and economic ties with China, the world's major engine for current global economic growth.
