HELSINKI, FEB. 27 – Finland supports a proposed U.N. peacekeeping mission in eastern Ukraine but sees problems in narrowing down participants to only selected European Union countries, Defense Minister Jussi Niinisto said on Tuesday, Reuters reported.

A report commissioned by former NATO chief Anders Fogh Rasmussen, now an adviser to Ukraine's President Petro Poroshenko, proposed earlier this month that the United Nations consider a force of about 20,000 soldiers from non-NATO countries to help resolve the crisis in Ukraine.
