The EU is signalling that Ukraine and Moldova are on a path away from Russian influence and towards greater integration with the West. The European Union will open membership talks with Ukraine on Tuesday, giving the country a political boost in the midst of its war against Russia's invasion, although a long and tough road still lies ahead before it could join the bloc. "The path to full-fledged membership, which Ukraine deserves ... is irreversible." ARDUOUS JOURNEYThe journey to EU membership is arduous for candidate countries, as they must reform to meet EU standards on a wide range of issues, from fighting corruption through regulating agriculture to harmonising customs rules. Candidate countries need approval from all 27 EU members to open and close each step of membership negotiations, giving EU governments numerous opportunities to hold up the process.
