European Union has imposed fresh sanctions on North Korea as part of international efforts to punish the pariah regime for its nuclear and ballistic weapons programmes. <br/><br/>Foreign ministers meeting in Luxembourg on Monday signed off a new package of measures including a ban on investments in North Korea and on EU exports of oil to Pyongyang. <br/><br/>They also tightened the restrictions on North Korean workers in the EU to try to stop money being sent home that could be used to fund the disputed weapons programmes. <br/><br/>The EU said the new steps were taken in view of the persistent threat to international peace and stability posed by Kim Jong-Un's regime.
