Asian black bear
Along with sun bears, Asiatic black bears are the most typically used species in areas where bears are either used in performances or as pets. Asian black bears have an outstanding learning ability in captivity, and are among the most common species used in circus acts. According to Gary Brown:
South East Asian Zoos Association
The Convention on International Trade of Endangered species CITES 
regulates all animal trade, rescue and reintroduction into the wild on the global level. However many countries in Southeast Asia view this agreement as a secondary concern. Most policies in Southeast Asia focus on the conservation of entire ecosystems and little on specific species that are endangered. Because Southeast Asia nations lack the resources to support both imperatives, SEAZA has a hard time enforcing the regulations of CITES prohibiting exhibiting some animals illegally and controlling the exportation of native species such as sun bears. 
Due to SEAZA’s inability to regulate some species, many private internationally conservations and organizations have stepped in for the protection and preservation of specific species such as Malaysian sun bear. The Ho Chi Minh City Zoo has a partnership with the Cologne Zoo in Germany. The Cologne Zoo works with SEAZA to conserve insect and reptile species, as well as working with Malaysia to rehabilitate the Malaysian sun bear species. In fact the Malaysian sun bear studbook is at the Cologne Zoo.
