This comes to an estimated 1.7 trillion dollars, their highest level since the financial crisis of 2008-09.Developing economies, as a whole, saw their FDI reaching a new high of 741 billion US dollars, which is 5 per cent higher than 2014, the report said. Asia remained the largest FDI recipient region in the world, surpassing half a trillion US dollars and accountingfor one-third of the global FDI flows, it said. The US bounced back as the top host country for FDI in 2015 with FDI worth 384 billion US dollars, the report said.
