Washington has told its Nato allies that it is more concerned about the future of Pakistan than Afghanistan and suggested the US will change its approach on Afghan drug policy.
Richard Holbrooke, US special representative for Afghanistan and Pakistan, told Nato ambassadors in Brussels that both countries' problems had to be tackled by working with neighbouring nations including Iran and China. President Barack Obama's administration favoured roughly doubling the size of the Afghan army and national police.
Mr Holbrooke's briefing came ahead of a US policy review, set to be concluded this week, which is expected to endorse continuing efforts to win over mid-level Taliban fighters from the ranks of the insurgents.
