The Chinese nationals, who arrived in Kathmandu from Istanbul on a Turkish Airlines flight yesterday, were found carrying the pangolin scales during an X-ray screening of their luggage in Red Channel Area of Tribhuvan International Airport Customs Office. “Our investigation shows that they bought the pangolin body parts in Congo of Africa and took the air route of Istanbul-Kathmandu,” he informed, adding that the Chinese nationals had made Nepal the transit point of the contraband. “We have established a transnational connection to this wildlife smuggling rink jointly by run by Congolese, Chinese, Bangladeshi and Nepali citizens. CIB is coordinating with the Interpol for more information about the foreigners associated with the smuggling racket,” SP Shrestha added.

Pangolin scales fetch around USD 3,000 per kg in the international black market. Pangolin scales are in high demand in Asian markets, especially China, as they are used in manufacturing bulletproof jackets and traditional Chinese medicine, a police source said.  Chinese people believe that pangolin scales can heal swelling, increase blood circulation and help mothers produce milk. The Convention on International Trade in Endangered Species has categorised the animal in Appendix I, which bans international trade in the species.
