Japanese Prime Minister Shinzo Abe urged fellow leaders of the Group of Seven advanced economies on Friday to avert another global crisis by acting to rescue the faltering global recovery. President Barack Obama backed Abe's call, saying it was crucial not just to put people back to work but also raise wages and maintain the momentum of the recovery. "We've all got a lot of work to do and we agreed to continue to focus on making sure that each country, based on its particular needs and capacities, is taking steps to accelerate growth," the U.S. president said. Abe and his counterparts got down to business after a morning stroll through the grounds of Ise Jingu, a tranquil, densely forested shrine that is considered the holiest site in Japan's indigenous Shinto religion.During the talks, Abe compared the current global economic situation to conditions just before the 2008 financial crisis. A G-7 summit held in northern Japan paid little attention to the trouble that was brewing, he said. "We learned a lesson that we failed to respond properly because we did not have a firm recognition of the risks," Abe told reporters. "This time, we had a thorough discussion and recognized the major risks facing the global economy."Japanese officials also highlighted joint efforts on corruption, terrorism, global health and migration — which has become a huge headache especially for European nations — as other top priorities. A possible exit from the European Union by Britain, depending on a June 23 vote, is also hanging over the talks. The annual summit brings together the leaders of Britain, Canada, France, Germany, Italy, Japan and the United States. It is taking place amid extraordinarily tight security around the remote summit venue, with uniformed police standing guard at close intervals on both sides of roads and randomly in forests, rice fields, soccer fields and other locations.The G-7 gathering dovetails in many ways with Abe's long-term diplomatic, political and economic agenda. A dramatic statement about global economic risks and a strong show of support for public spending to help spur growth could help Abe justify extra stimulus and possibly provide political cover for postponing an unpopular but badly needed increase in Japan's sales tax next April. Many of the issues to be discussed are linked to other Abe policy priorities, including maritime security, code for concerns over China's expanding presence in disputed areas of the South China Sea.
