We reaffirm our strong commitment to bring the Doha Development Agenda to a prompt and successful conclusion. Bearing in mind that 2011 will be a critically important "window of opportunity," we direct our Ministers to empower our representatives to engage in comprehensive negotiations with a sense of urgency in the end game, built on the progress achieved, including with regard to modalities, consistent with the Doha mandate. We affirm our commitment to win domestic support in our respective systems for a strong agreement. In our continued efforts to resist protectionism, we agree to extend our commitment on standstill made in 2008 to the end of 2013 to refrain from raising new barriers to investment or to trade in goods and services, imposing new export restrictions, or implementing World Trade Organization inconsistent measures in all areas, including those that stimulate exports. We commit to take steps to rollback trade distorting measures introduced during the crisis. Furthermore, we will continue to exercise maximum restraint in implementing measures that may be considered to be consistent with WTO provisions if they have a significant protectionist effect and promptly rectify such measures where implemented.
