China's President Xi Jinping warned Sunday that the global economy remained in a precarious condition as leaders of the BRICS group of nations tried to find ways to fire up growth in the troubled bloc. Speaking at a summit in the Indian state of Goa, Xi told his host Narendra Modi and the leaders of Russia, Brazil and South Africa that the club of emerging powers had been undermined by both domestic and international woes. But the leader of the world's second largest economy said the long-term forecast for BRICS members was positive as he called for more confidence-building measures."The global economy is still going through a treacherous recovery," Xi said in a statement at the summit on India's west coast. "Because of the impact of both internal and external factors, BRICS countries have somewhat slowed down in economic growth and have faced a number of new challenges in development."BRICS was formed in 2011 with the aim of using members' growing economic and political influence to challenge Western hegemony. The nations, with a joint estimated GDP of $16 trillion, set up their own bank in parallel to the Washington-based International Monetary Fund and World Bank and hold summits rivalling the G7 forum. But the countries, accounting for 53 percent of world population, have been hit by falling global demand and lower commodity prices, while several have also been mired in corruption scandals. Russia and Brazil have fallen into recession recently, South Africa only just managed to avoid the same fate last month and China's economy has slowed sharply. India by contrast is now the world's fastest-growing major economy in an otherwise gloomy environment. Modi said it was vital that the BRICS nations found ways of increasing their levels of cooperation. He called for the dismantling of trade barriers, promotion of skills and infrastructure development.
