Chinese President Xi Jinping said that the global economic economy remained treacherous as he attended a summit of BRICS leaders in India on Sunday.

"The global economy is still going through a treacherous recovery," Xi said in a statement at the summit in the coastal state of Goa.

"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."
