The Agreement on Trade-Related Investment Measures (TRIMS) recognizes that certain investment measures can restrict and distort trade.  It states that WTO members may not apply any measure that discriminates against foreign products or that leads to quantitative restrictions, both of which violate basic WTO principles.  A list of prohibited TRIMS, such as local content requirements, is part of the Agreement.  The TRIMS Committee monitors the operation and implementation of the Agreement and allows members the opportunity to consult on any relevant matters.
