Among a small number of ambassadors who remain in Kabul, Wang Yu, Chinese ambassador to Afghanistan, appears the busiest.
This week, Wang met with three Taliban ministers, two of whom are particularly shunned by Western diplomats - Sirajuddin Haqqani, the interior minister who has a $10 million terrorism bounty over his head from the United States, and Nida Mohammad Nadem, the higher education minister who has closed universities for Afghan girls.
