The EU member states said in a statement Monday they will restrict trade in coal and iron and ban imports of several other metals. The EU also imposed a ban on helicopter and ship exports and tighten restrictions in the financial services after the U.N. decision of November.
Measures include bans on the trade of arms, goods and technology that could contribute to the programs.

Such sanctions are imposed with the aim to increasingly isolate the Asian country politically and economically.
