The top UN envoy in Kabul said Thursday the international strategy to help Afghanistan was basically sound but he hoped the incoming US administration would inject it with new energy.

The government of Barack Obama, to be sworn in on January 20, is expected to review its strategy here amid an increase in violence and instability, and questions about development in the country since the Taliban regime was ousted in 2001.

"I don''t think there is anything basically wrong with the strategy," Kai Eide told AFP in an interview. "But I think we do not implement well enough what we are doing, what we have agreed on."

Afghanistan''s partners had agreed on priorities such as improving security, including through police reform, and developing the economy and human capital, he said.

The Norwegian diplomat said he hoped "the Obama administration will bring new energy, new strength in implementing what we have agreed on, which basically are the right priorities."

"When the new US administration comes in, it''s a tremendous opportunity to inject new energy into that," Eide said.
