Could Chinese banks cutting off money flow to the Democratic People's Republic of Korea (DPRK) make the difference in stopping the nuclear crisis on the Korean Peninsula? US President Donald Trump said Thursday that China's central bank has ordered the country's banks to curb trade with the DPRK, as he announced new US sanctions against Pyongyang. The Chinese move, which Trump described as "very bold" and "unexpected," was not immediately confirmed by Beijing, but if it's true, it could cut a vital source of foreign currency for the DPRK government.
