China is to build its first naval base in Djibouti, the Djiboutian foreign minister said Friday, in the latest sign of China's growing international security presence.

Djibouti is seen as a key strategic location in the Horn of Africa, with United States, France and Japan already having facilities in the country.

"The negotiations have come to an end and the naval base will be built in Djibouti," Mahamoud Ali Youssouf told AFP on the sidelines of a summit of African leaders in Johannesburg.

"The goal of the base is to fight against pirates... and most of all to secure the Chinese ships using this very important strait that is important to all the countries in the world."

"For Djibouti, it's an additional strategic ally."

A former French colony, Djibouti guards the entrance to the Red Sea and, ultimately, the Suez Canal, and has been used by international navies as a hub in the fight against piracy from neighbouring Somalia.

"For a few years with the instability in Somalia, this region has become a refuge for pirates and the terrorist movements," Youssouf said.

In May, Djibouti's President Ismail Omar Guelleh told AFP that talks over the military base were underway.

Guelleh met with Chinese President Xi Jinping at the summit in Johannesburg, where China announced $60 billion of assistance and loans for Africa.

China announces $60 billion 'funding support' for Africa
Johannesburg (AFP) Dec 4, 2015 - Chinese President Xi Jinping announced $60 billion of assistance and loans for Africa at a summit in Johannesburg on Friday, signalling China's commitment to the continent despite a recent fall in investment.

China's economic growth has taken a dip this year, triggering a global commodities slump and causing Beijing to slash investment in Africa by more than 40 percent in the first six months of 2015.

Xi said that China would "provide a total of $60 billion of funding support that includes $5 billion of grants in zero interest loans (and) $35 billion in preferential facility and export credit loans and concessional loans."

In a slew of pledges at his speech opening the Forum on China-Africa Cooperation (FOCAC), he also announced drought aid for the continent.

"China is greatly concerned about the poor harvest caused by El Nino in many African countries and will provide one billion renminbi yuan ($156 million) worth of emergency food aid to the affected countries," he said.

The two-day FOCAC meeting is the second time China has brought together African leaders since the forum was launched in Beijing in 2000.

Since then, China's trade with Africa has overtaken that of the traditional partners, Europe and the United States.

"China is still very active in Africa," Deborah Brautigan, of the US-based China Africa Research Institute, told AFP.

"They are very competitive. They made it clear that Africa is still their business partner (but) this big sum is mainly loans that will have to be repaid."

The money will target 10 areas, including industrialisation, infrastructure, financial services, poverty reduction, and peace and security.

Zhong Jinahua, a Chinese diplomat at the summit, brushed off concerns about the recent drop in investment into Africa.

"I don't think we need to panic over the fluctuation in trade volumes," he told reporters. "It's only natural for the market to experience some ups and downs."

- Mining lay-offs -

A fall in mineral prices has hit African countries who relied on Chinese demand, with large lay-offs by mining companies in resource-rich countries such as Zambia and South Africa.

"We are keen to explore cooperation with China to ensure the long term viability of African mining," South Africa President Jacob Zuma told the summit.

"This is important in light of the declining demand for commodities."

Among the presidents attending were Muhammadu Buhari of Nigeria, which is Africa's largest economy, Salva Kiir of South Sudan, Joseph Kabila of the Democratic Republic of Congo and Kenya's Uhuru Kenyatta.

Xi -- accompanied by his wife Peng Liyuan -- landed in South Africa after a brief visit to Zimbabwe, where Chinese projects have helped prop up an economy plunged into crisis under President Robert Mugabe's rule.

Mugabe, who addressed the summit's opening session as chair of African Union, lavished praise on the Chinese leader.

"We say he is a god-sent person," Mugabe said. "President Xi Jinping has made a much anticipated announcement of new measures... to inject vibrancy into that already dynamic relationship between China and Africa.

"Our detractors have sought to portray our relationship to purely commercials ties, driven by China's desire to extract our mineral resources, (but) our relations go much deeper."

Sudanese leader Omar al-Bashir, who is wanted by the International Criminal Court (ICC) on charges of genocide, war crimes, and crimes against humanity, was not expected to attend the Johannesburg event.

He attended an African Union summit in the city earlier this year, leading to a huge furore when South Africa declined to arrest him despite a court order.
