Obama meets with European leaders at G-20 Summit The two-day summit concludes Tuesday President Obama will hold a news conference after it ends Obama also will meet with Chinese President Hu Jintao Summit looking at the eurozone crisis and how to boost global economic growth Los Cabos, Mexico (CNN) -- U.S. President Barack Obama met Tuesday with European leaders on the sidelines of the G-20 Summit aimed at boosting a sluggish global economic recovery threatened by a possible collapse of the euro currency union. Obama also will meet with Chinese President Hu Jintao, and then hold a news conference to conclude the two days of talks by leaders of the world's major developed and emerging economies. The summit has largely focused on one of the primary causes of the global economy's lethargic recovery -- the threat of a European currency collapse that would roil the already fragile economies of most of the 17 countries that use the euro. Summit leaders were to release a declaration Tuesday summarizing economic objectives. While most of the formal summit sessions so far -- including two rounds of talks and a working lunch Tuesday -- were in private, Obama and other leaders offered comments to reporters during brief photo sessions at their bilateral meetings. "The world is concerned about the slowing of growth that has taken place," Obama said Monday following one-on-one-talks with host President Felipe Calderon of Mexico. However, the summit was not expected to produce concrete commitments, and European Union President Jose Manuel Barroso made clear that European nations were not there to be lectured on how to proceed. This crisis was not originated in Europe. ... And many of our financial sectors were contaminated by -- how can I put it -- unorthodox practice from some sectors of the financial market. Obama also had bilateral meetings Monday with other leaders, including his first face-to-face talks with Russian President Vladimir Putin since Putin recently returned to the post after serving as prime minister. Speaking to reporters after almost two hours of talks, Obama said he and the Russian leader discussed the conflict in Syria and "agreed that we need to see a cessation of the violence, that a political process has to be created to prevent civil war." Putin said the two leaders were "able to find many commonalities" on a range of issues, but provided no details. Earlier, Obama and Calderon held talks that included the announcement that Mexico would join the United States and eight other countries in negotiations on the Trans Pacific Partnership, an economic union to boost trade. In addition to the United States, the current countries of the partnership are Australia, Brunei, Chile, Malaysia, New Zealand, Peru, Singapore and Vietnam. A main topic of the summit was Sunday's elections in debt-ridden Greece, where the center-right New Democracy party received the most votes and was asked to try to form a coalition government.
