Afghanistan's new Taliban administration has warned the US and European envoys that continued attempts to pressure them through sanctions will undermine security and could trigger a wave of economic refugees.

Axar.az reports citing foreign media that acting foreign minister Amir Khan Muttaqi told Western diplomats at talks in Doha that "weakening the Afghan government is not in the interest of anyone because its negative effects will directly affect the world in (the) security sector and economic migration from the country", according to a statement published late Tuesday.

The Taliban overthrew Afghanistan's former US-backed government in August after a two-decade-long conflict, and have declared an Islamic emirate governed under the movement's hardline interpretation of religious law.

But efforts to stabilise the country, still facing attacks from the rival extremist groups the Daesh-Khorasan, have been undermined by international sanctions: banks are running out of cash and civil servants are going unpaid.
