Angola's embassy in Beijing has been issuing up to 500 visas every day this year for Chinese to travel to the southern African country, state news agency Angop reported on Wednesday.

"We're issuing on average 400 to 500 visas per day," more than "the 200 initially anticipated," Ambassador Joao Manuel Bernardo was quoted as saying.

Joao Bernardo said the increased number of visa requests was due to the high demand for specialised labour by Chinese and Angolan construction companies which are engaged in multiple projects in the formerly war-torn nation.

China's links with Angola have been expanding rapidly since Angola's 27-year war ended in 2002. The southwest African nation is now one of China's main sources of oil.
