Foreign investment

As part of its WTO accession, China undertook to eliminate certain trade-related investment measures and to open up specified sectors that had previously been closed to foreign investment. New laws, regulations, and administrative measures to implement these commitments are being issued. Major remaining barriers to foreign investment include opaque and inconsistently enforced laws and regulations and the lack of a rules-based legal infrastructure. Warner Bros., for instance, withdrew its cinema business in China as a result of a regulation that requires Chinese investors to own at least a 51 percent stake or play a leading role in a foreign joint venture.
