President Donald Trump announced Thursday that he had signed an executive order authorizing additional sanctions against North Korea by targeting individuals, companies and financial institutions that do business with what he called "this criminal rogue regime." The president said that for 25 years North Korea had been allowed to get away with “abuse” of the international financial system to fund its weapons development program. Trump noted that he'd signed the executive order just as China's central bank "has told their other banks ... to immediately stop doing business with North Korea."
