Following WTO regulations, China has committed itself to cutting tariffs, liberalizing its domestic distribution practices, and restructuring its regulatory environment. China has allowed foreign enterprises to import products and engage in distribution services. Furthermore, China has also implemented new drug administration laws designed to product registration and protect Intellectual Property Rights (IPR). China has agreed to six years of "data exclusivity" and has committed itself to implementing a patent linkage system. The SFDA has worked to crack down on counterfeiters but without greater resources and stricter legal consequences, these actions alone have yet to be enough to curb this rampant problem.
