China will build a base for police in Tajikistan near the Afghan border, a Tajik official said Thursday, amid concerns from both countries about the Taliban's ability to keep a lid on extremist groups. The base points to deepening security cooperation between impoverished Tajikistan and China, which is reported to maintain another base in the southeast of the ex-Soviet country. A parliamentary spokesman told AFP that Tajikistan's lower house had approved the plan to build the base in the Ishkashim district of the mountainous Gorno-Badakhshan province.
