Xi Jinping, China’s president, defended his country’s role in Africa and promised increased investment during his first overseas trip as head of state, countering growing criticisms from African officials who say China’s role is “predatory” with echoes of colonialism.

Speaking at a Chinese-built conference centre in Dar es Salaam, Tanzania, Mr Xi underscored China’s longstanding policy not to interfere in domestic politics, praised Africa’s economic growth and reaffirmed China’s pledge of $20bn in loans to Africa over the next three years. He also signed an agreement to build a large port and industrial zone in Tanzania, which officials say could cost up to $10bn.

“The African lion is galloping faster and faster, while China also maintains a good development momentum,” said Mr Xi. “We each view the other’s development as our own opportunity.”
