There are various reasons why foreign investors use offshore                      companies to structure their investment in China. Offshore                      companies add an additional layer of limited liability, removing                      risk from its valuable parent company. Corporate law of offshore                      jurisdictions is often very flexible. Sale of the investment                      in China can be made by transferring the offshore entity,                      rather than the stake in the Chinese entity, which saves bureaucratic                      hassles in China. 
Most importantly, offshore corporations can be used for tax                      planning purposes. By correctly arranging financial affairs,                      significant tax savings can be achieved -- but it should be                      noted that some schemes may constitute illegal tax evasion,                      rather than legal tax planning, so great care should be taken                      before setting up in one of these jurisdictions. Offshore                      jurisdictions are typically small islands in exotic locations.                      Examples are the Cayman Islands, British Virgin Islands, Samoa                      and Mauritius. Hong Kong is also a popular jurisdiction, due                      to its special status and proximity to the mainland. 
It should be noted, however, that removing the administration                      of a company far from China causes practical difficulties,                      for instance when opening a bank account or when verifying                      documents. 
All in all, offshore companies offer many advantages to investors,                      but there are many traps one could fall into. Therefore, sound                      legal advice should be sought before setting up an offshore                      company as an investment vehicle in China.
