(Corrects paragraph 2 to show that contracts concluded before June 25 are not affected)
BRUSSELS (Reuters) - New European Union economic sanctions on Belarus prohibit any import or transport of products including potash, petroleum and tobacco, while banning new loans or dealings in longer-term securities, the bloc's official journal said on Thursday.
The EU imposed the sanctions earlier in the day but do not affect contracts concluded before June 25, the journal said. They affect institutions whose state participation was 50% as of June 1 this year.
The sanctions mean Belarus, the world's largest producer of potash, will face a challenging task to find other countries to transport the fertiliser ingredient via the Baltic Sea.
