Mogherini's decision came one day after the Council of the European Union broadened a sanction list targeting North Korea in response to its latest test-launch of ballistic missiles.
"This resolution was adopted on 5 August 2017 in response to the Democratic People's Republic of Korea (DPRK)'s ongoing nuclear-weapon and ballistic missile-development activities, in violation and flagrant disregard of previous UN Security Council resolutions", the statement noted.
The EU move means that 62 people and 50 entities, like companies, organizations or banks, are now under sanctions in line with the United Nations list. The EU has a policy of critical engagement towards North Korea and its goals are to support a lasting diminution of tensions on the Korean peninsula and uphold the global non-proliferation regime.
The EU's sanctions are seen as its efforts to intensify pressure against North Korea amid the escalating war of words between Pyongyang and Washington. "Hopefully Kim Jong Un will find another path!" The document also obliges states not to allow vessels into their ports if they were reported as violating the sanctions regime by the UN Security Council's special committee, with exception given to cases of emergency.
Last month, North Korea tested two intercontinental ballistic missiles, at least one of which experts believe could reach deep into the continental U.S.
Trump warned North Korea on Tuesday it will be met with "fire and fury" if it continues to threaten his country.
And a day later, he told reporters at his golf club in Bedminster, New Jersey, that his administration is looking at military options "very carefully". Some could reach the mainland US, according to Pyongyang.
