Wildlife trafficking from Mexico to China receives little international attention, but it is growing, compounding the threats to Mexican biodiversity posed by preexisting poaching for other markets, including the United States. Since Mexican criminal groups often control extensive territories in Mexico which become no-go-zones for government officials and environmental defenders, visibility into the extent of poaching, illegal logging, and wildlife trafficking in Mexico is limited. It is likely, however, that the extent of poaching and trafficking, including to China, is larger than commonly understood.
