The Foreign Ministry said China had sent escort fleets to the Gulf of Aden and Somalia in recent years, and these fleets had experienced difficulties that affected the "rest and reorganization of servicemen and the supply of oil".

"It (the outpost) is essential to implement highly efficient logistical support," the ministry said.

In December, the Ministry of National Defense confirmed that China and Djibouti had reached agreement on the outpost. Military bases and support facilities for countries including the United States and France have long been based in Djibouti.

Djibouti's Foreign Minister Mahamoud Ali Youssouf told Reuters, "We understand that some Western countries have worries about China's willingness to have military outposts outside of China." He said that Western countries should not be concerned.

Djibouti is a pivotal country in the Horn of Africa standing between the Red Sea and Gulf of Aden. It is a key transfer stop for international humanitarian missions, including those of the United Nations.

Yin Zhuo, director of the People's Liberation Army Navy's Expert Consultation Committee, estimated that a Chinese fleet patrolling waters in the region has to feed about 800 staff members every day. A single mission, which lasts on average for 120 days, places a huge demand on food and water supplies.

Zhang Junshe, a senior researcher at the PLA Naval Military Studies Research Institute, said Djibouti is one of the closest major ports to Somalia. Its peaceful environment makes it an ideal place to host China's support facility.

Zhang said the outpost that China is expected to build there is designed to provide food, water and oil. It would be totally different from US military bases, which supply weaponry, Zhang added.

Djibouti's strategic importance and logistical convenience were highlighted last year when Chinese citizens evacuated from Yemen transited there.
