"The WTO also adapted to play a crucial role in constraining the rise in protectionism. The WTO's impact was felt through both enhanced monitoring and acting as a focal point for plurilateral liberalization. Beginning in late 2008, the WTO's secretariat used the Trade Policy Review Mechanism to report on a regular basis to the G20 on increases in protectionism. After initial reluctance, WTO members accepted the move as a useful increase in monitoring and transparency. A comparison of the WTO's monitoring with that of Global Trade Alert further shows that the monitoring of the latter is based on less reliable metrics and exaggerates the increase in protectionism. WTO members also shifted their approach to pushing for greater trade liberalization by switching to expanding or starting plurilateral agreements. China is now negotiating to join the Government Procurement Agreement. The United States, the European Union, and eighteen other countries have accelerated talks on a services liberalization agreement that would encompass most of the OECD economies as well as advanced developing countries" Discuss?
