There have been however some concerns expressed by the WTO. According to Pascal Lamy, Director-General of the WTO, the proliferation of regional trade agreements (RTAs) "...is breeding concern — concern about incoherence, confusion, exponential increase of costs for business, unpredictability and even unfairness in trade relations." The position of the WTO is that while the typical trade agreements (called "preferential" or "regional" by the WTO) are useful to a degree, it is much more beneficial to focus on global agreements in the WTO framework such as the negotiations of the current Doha round.
