Zimbabwe’s new China-funded hilltop parliament building is complete and ready to be handed over to the authorities three-and-a-half years after construction began.

It sits 18km (11 miles) north-west of the capital, Harare, and is part of a plan to decongest the city centre.

Journalists were allowed to see the finished complex, which cost an estimated $140m (£115m), during a tour given by the Chinese contractors. Five hundred Chinese technicians and 1,200 local employees worked on the construction.

The sprawling 3.3-hectare (eight-acre) campus is a gift from Beijing and aimed at “strengthening the solidarity and friendship between the people of Zimbabwe and China”, China-Aid project manager Cai Libo told reporters.

China has been a long-standing ally of Zimbabwe. It financially and militarily backed the liberation struggle against white-minority rule, when the country was known as Rhodesia.

But China has itself now been accused of neo-colonialism and for unfairly exploiting the country's mineral resources.

Outside the parliament building, two long stone staircases flank a water feature that is supposed to represent Victoria Falls.

The building's circular chevron-laced edifice echoes Zimbabwe’s landmark of Great Zimbabwe.

And inside, the national assembly, with seats for 350 MPs, is built in a circular style - a break from the current arrangement which copies the Westminster format where government and opposition sit on opposite benches.

On the ceiling is a painting copying pre-historic rock art that has been found in Zimbabwe.

There is also the upper house of parliament with room for 100 senators.

No date for when parliament will actually move has been given.
