In 2007, Myanmar promulgated the Wildlife and Aquatic Products Law, which prohibited the use of some animals. Like tigers and bears. But the loophole in the law is that people can use these animals if they get permission from the government! Secondly, the second generation of captive animals can be used for trading and need to be registered by the Lao government.
At present, except China, eating tiger meat is prohibited all over the world, including internationally. But some people can't help being greedy and doing illegal and criminal transactions.
