BEIJING, Jan. 16 -- The gross product value generated by China's marine industry in 2013 is expected to reach 5.4 trillion yuan (893.4 billion U.S. dollars), up 7.9 percent year on year, according to a national maritime work conference on Thursday.
China finished a survey of the country's islands, identifying a total of 11,933 islands, with 3,481 of them newly named. It compiled a list of standard names and an atlas of the islands, according to the conference.
In 2013, China also established a monitoring system for the islands and set up a database of information about them.
Last year, Chinese vessels continued patrols in the territorial waters surrounding the Diaoyu Islands to maintain the country's maritime rights and achieved effective management and control over Huangyan Island.
Since August 2013, Chinese ships have carried out patrols in the territorial waters around Beikang Ansha and Nankang Ansha, according to the conference.
