The new Greek government has unexpectedly halted the sale of its Piraeus Port to China's Cosco (China Ocean Shipping (Group) Company) Group. ANBOUND research team observes that Greece’s move has placed China’s Cosco and government in a passive position, highlighting the fact that political risks in an era of capital net export are not allowed to be ignored. In the process of advancing "one belt and one road" strategy, China is likely to face similar cases repeatedly, which are to challenge risk management capacities of both governments and enterprises.
