AlHijjah 16, 1435, Oct 10, 2014, SPA -- The Group of 20 major advanced and emerging economies on Friday identified boosting investment in infrastructure as "critical" for hopes to spur global economic growth. "While some key economies are recovering, others face renewed weakness," G20 finance ministers and central bankers said in a joint statement after meeting in Washington. "But we have emerged with optimism. We are determined to achieve outcomes that will strengthen the recovery." The G20 plan is meant to raise global gross domestic product by 1.8 per cent over five years, adding 2 trillion dollars and millions of jobs to the world economy.
