Legal Thoughts on Free-Trade Area:Mode,Foundation and Structure

Generally, there are two modes for Free-Trade Area, one is unilateral, the other is bilateral, or multilateral. However, theoretically, Bilateral or Multilateral Free-Trade Area may be defined as two types, Common-bilateral or Common-multilateral Free-Trade Area, and Sub-bilateral or Sub-multilateral Free-Trade Area. For the international economic trade rules, the legal foundation is sufficient and mature enough to build up a Unilateral Free-Trade Zone and a Bilateral or Multilateral Free-Trade Area. Nevertheless, there is too much debate around the validity of Sub-bilateral or Sub-multilateral Free-Trade Area. Moreover, with the rapid development of economy globalization currently and the reference of the experience of other countries or areas, it has come to be a valuable argumentation to establish a complete legal structure for the Unilateral Free-Trade Zone.
