The head of the African Development Bank (AfDB) has heaped praise on Tanzania's President John Magufuli after the country posted annual economic growth figures of 7%.

AfDB President Akinwumi Adesina, who was visiting the head of state on Wednesday in Dar es Salaam, said the country's growth rate is one of the highest in the world, and compares well to the global GDP growth rate at just about 3.5%.

He described President Magufuli as a bold reformer, and a focused and determined man.

Mr Adesina said he was impressed that Mr Magufuli was working with other neighbouring countries, particularly with Uganda, on the construction of an oil pipeline.

The Tanzanian president has been criticised by human rights groups for cracking down on independent media and arresting opposition members.
