Afghanistan arrested and handed over several Muslim Uighur militants from China's west in an effort to persuade China to use its influence with Pakistan to help start negotiations with the Taliban, Afghan security officials said on Friday.

The deal sheds light on China's increasing importance in Afghanistan and Pakistan as it becomes involved in efforts to end the war with the Taliban, who have been fighting since 2001 to re-establish Islamist rule in Afghanistan.

Hopes for a peace process were raised on Thursday when Pakistani and Afghan officials said members of the Taliban leadership had signaled they were willing to begin talks as soon as next month.
