China is to revise its 1984 Maritime Traffic Safety Law, which would allow the relevant authorities to bar some foreign ships from passing through Chinese territorial waters.

The Legislative Affairs Office of the State Council announced Tuesday it is soliciting public opinions on the revisions.

The draft would empower maritime authorities to prevent foreign ships from entering Chinese waters if it is decided that the ships may harm traffic safety and order.

The draft revisions stipulate that authorities will be able to designate specific areas and temporarily bar foreign ships from passing through those areas according to their own assessment of maritime traffic safety.

The revisions are based on the UN Convention on the Law of the Sea and Chinese laws on the sea, adjacent areas and exclusive economic zones, the office said.

Wang Xiaopeng, a maritime border expert at the Chinese Academy of Social Sciences, told the Global Times on Wednesday that the revisions will provide legal support for China to safeguard its maritime rights.

"As a sovereign State and the biggest coastal State in, for example, the South China Sea, China is entitled to adjust its maritime laws as needed, which will also promote peace and stable development in the waters," Wang said.

Yang Cuibai, a professor with the School of Law at Sichuan University, agreed, saying that "the revisions will strengthen China's management over territorial waters in a new era when the country's communication and trade with foreign countries in the waters have sharply increased."

Yang added that China should take the lead to establish the legal order in the Yellow Sea, the East China Sea and the South China Sea.

Foreign submersibles should travel on the surface, display national flags and report to Chinese maritime management administrations when they pass China's water areas, the draft says. They should also get approval from the relevant administrations to enter China's internal waters and ports.

Foreign military ships that are approved to enter China's waters should apply for pilotage. Foreign ships that enter Chinese waters without approval will be fined 300,000-500,000 yuan ($43,706-72,844) and those violating Chinese laws would be expelled, it said.

"China's waters are open to foreign ships as long as they do not damage the waters' safety, order, or China's sovereignty," Yang said.

The draft also states that people in distress at sea have the right to be rescued without charge, adding that human lives should come before the environment and assets.

The State Council and local governments should set up maritime search and rescue centers, if needed, to organize, coordinate and command rescue operations, the draft says. Civilian groups are also encouraged by the revised regulations to set up rescue teams and participate in such operations.

The revisions will take effect in 2020.
