Ships carrying personnel for China's first overseas military base have set sail to begin setting up the facility in Djibouti, as the country's rapidly modernising military extends its global reach.
The warships departed from Zhanjiang in southern China to set up a "support base" in the Horn of Africa nation, state media reported late on Tuesday.
China's agreement with Djibouti ensures its military presence in the country up until 2026, with a contingent of up to 10,000 soldiers, according to international current affairs magazine The Diplomat.
Djibouti's position on the northwestern edge of the Indian Ocean has fuelled worry in India that it would become another of China's "string of pearls" of military alliances and assets ringing India, including Bangladesh, Myanmar and Sri Lanka.
China began construction of a base in Djibouti last year. It will be used to resupply navy ships taking part in peacekeeping and humanitarian missions off the coasts of Yemen and Somalia, in particular.
It will be China's first overseas naval base, though Beijing officially describes it as a logistics facility.
State news agency Xinhua did not say when the base would begin operations.
Xinhua said the establishment of the base was a decision made by the two countries after "friendly negotiations, and accords with the common interest of the people from both sides".
"The base will ensure China's performance of missions, such as escorting, peace-keeping and humanitarian aid in Africa and west Asia," it said.
Foreign ministry spokesman Geng Shuang told a daily news briefing the base would enable China to make "new and greater contributions" to peace in Africa and the world and would benefit Djibouti's economic development.
Djibouti, which is about the size of Wales, is at the southern entrance to the Red Sea on the route to the Suez Canal.
The tiny, barren nation sandwiched between Ethiopia, Eritrea and Somalia also hosts US, Japanese and French bases.
The People's Liberation Army Daily said in a front-page commentary that the facility was a landmark that would increase China's ability to ensure global peace, especially because it had so many UN peacekeepers in Africa and was so involved in anti-piracy patrols.
The state-run Global Times said in an editorial that there could be no mistake that this was in fact a military base.
"Certainly this is the People's Liberation Army's first overseas base and we will base troops there. It's not a commercial resupply point. It makes sense there is attention on this from foreign public opinion," said the paper, which is published by the official People's Daily.
