G8 Leaders Criticize North Korea, Iran, Urge Progress in Afghanistan Dan Robinson | Toronto 26 June 2010 General view of a G8 summit working session at the Deerhurst Resort in Hunstville, Ontario, 26 Jun 2010 Photo: AFP General view of a G8 summit working session at the Deerhurst Resort in Hunstville, Ontario, 26 Jun 2010 World leaders meeting at the G8 summit in Canada turned their attention to global security issues as wrapped up business of the Group of Eight (G8) and transitioned to a larger summit of the G20. A final communique from the world's eight major industrial democracies condemns the sinking of a South Korean warship, blamed on North Korea, criticizes criticizes Iran on human rights and the rule of law, and addresses the situation in Afghanistan. G8 leaders condemn the sinking of the South Korean warship this past March that an international investigation said was carried out by North Korea. They call on Iran's leaders to respect rule of law and freedom of expression. On Afghanistan, the G8 presses the government of President Hamid Karzai to demonstrate tangible progress in time for a key conference next month, that it is taking on greater responsibility for security. Addressing a key tension spot in the Middle East, the draft communique calls current tensions in Gaza "unsustainable. Canadian Prime Minister Stephen Harper also delivered this message where Iran and North Korea are concerned. "The governments of Iran and North Korea have chosen to acquire weapons to threaten their neighbors," he said. "The world must see to it that what they spend on these weapons will not be the only cost that they incur." G8 leaders now shift to Toronto for the larger G20 summit, including the G8 nations - the U.S., Canada, Britain, France, Germany, Russia, Italy, Japan - and major developing economic powers such as China and India. As the G20 got underway, Afghanistan was a key topic in President Obama's first face-to-face meeting with British Prime Minister David Cameron, also likely to include discussion of the transition to a new U.S. And NATO commander, General David Petraeus. Before the G8 summit, the two leaders discussed shared strategy for Afghanistan and Pakistan, and underscored what the White House called their firm commitment to the NATO mission in Afghanistan. After comments Mr. Cameron made to Sky Television that he would like to see British troops leave Afghanistan by 2015, senior U.S. administration officials said the U.S remains comfortable with commitments from allies in Afghanistan. U.S. forces are supposed to begin a conditions-based draw down in July of 2011. On Iran, leaders discussed implementation of the U.N. Security Council resolution imposing significant new sanctions for Iran's defiance of international demands to halt its uranium enrichment program, which western powers say is aimed at developing a nuclear weapon. President Obama's talks with China's President Hu Jintao are likely to cover, in addition to Iran, Beijing's implementation its pre-summit decision to allow its currency to rise in value against the U.S. dollar. Asked about the conclusions of the G8 on economic issues, Canadian Prime Minister Harper summarized a concern he said all leaders shared: the need to avoid a repeat of risks, and events, that led to the 2008 financial crisis. "We can't afford some particular event that would cause a series of cascading events and a downward spiral of confidence in global markets," he said. Harper said he has never been at a G8 summit where leaders seemed to more deeply feel the necessity of common action and purpose and more fundamentally united in purpose. What the wider G20 group will say about the global economy remains to be seen, though there have been indications of the direction a final communique may take when the summit concludes on Sunday. At the G8, leaders such as Germany's Angela Merkel underscored domestic pressures they face to bring down deficits and control spending. President Obama emphasized the importance of maintaining durable economic growth, and the risks of sharply reducing stimulus spending. .
