Pakistan will review its 'lenient' visa policy for Chinese nationals to plug the loopholes in the current system, weeks after the killing of two Chinese 'missionaries' who entered the country on business visas.

The conditions and requirements for issuance of business and work visas to the Chinese nationals will be reviewed, the Interior Ministry said in a statement yesterday. The decision comes days after Interior Minister Chaudhry Nisar Ali Khan had been informed that the murdered Chinese citizens were missionaries who were part of a group of Chinese nationals which obtained business visas and entered Pakistan.
