The visit comes against the backdrop of mounting challenges to Western support for Ukraine and growing field losses against the Russian military.

These challenges are compounded by the absence of a clear exit strategy.

The EU is also planning to resort to frozen Russian sovereign funds for the "future reconstruction of Ukraine," as it claims.

Last week, the bloc agreed to a €50 billion in aid to Ukraine and a new package of sanctions, banning around 200 new individuals from traveling to the EU.
