US President Donald Trump vowed to impose additional "major sanctions" against North Korea on Wednesday in response to its latest groundbreaking missile test. "Just spoke to President XI JINPING of China concerning the provocative actions of North Korea," Trump tweeted. "Additional major sanctions will be imposed on North Korea today. This situation will be handled!"
Secretary of State Rex Tillerson explained that the sanctions would be announced by the US Treasury and would target "additional financial institutions." This suggests that secondary measures could target foreign banks that still deal with North Korea. A Chinese bank has already been hit in this way. "We have a long list of additional potential sanctions," Tillerson told reporters.
Asked how long Washington could continue to mount peaceful pressure on Pyongyang without resorting to military action, Tillerson said: "Diplomatically, we keep working at it every day."
