The EUCommission president was frank about the challenges facing the bloc.
I believe thenext 12 months are decisive if we want to reunite our union, if we want toovercome the divisions between East and West, which have opened up in recentmonths, he said.
Those divisionsthreaten to overshadow the informal meeting of EU heads of state scheduledFriday in Bratislava.
Some of theseissues between member states of the EU are existential, they're not simply amatter of personalities. They are about the construction of the European Union,said Stephen Booth.
Eastern memberstates, including Slovakia, have resisted Brussels' plans for a compulsoryquota system to resettle refugees across the EU. The dispute escalated thisweek when Luxembourg's foreign minister said Hungary should be expelled fromthe bloc for its hardline stance on the refugee crisis, which included erectinga border fence to keep out migrants.
I am urging theSlovak presidency to bridge the divergences and differences between those whoare reluctant to integrate refugees in their societies and those who are convinced,as I am, that the fair share in the relocation and resettlement is of theessence, said the EU President..
But thedivergences between east and west go beyond the refugee crisis, says analystStephen Booth.
"Particularlyafter the Brexit vote, the eastern European member states talk much more aboutsort of transferring power away from the institutions. But I think some of thedynamics aren't just between east and west. They are actually between theBrussels institutions, their view of what the EU might and should look like,and an increasing desire from all member states to sort of have a much moreintergovernmental approach," he said.
The Brexit votestill dominates debate in the EU, but in seeking a common cause to unify afractured union. UK proposed stronger military cooperation.
"We musthave a European headquarters. We must also organize ourselves to work toward acommon military force and this should be in complement with NATO. More Europeandefense in Europe doesn't mean less transatlantic solidarity," said the EUPresident.
A commonEuropean Union military force was something Britain had long resisted, but itsinfluence is already diminished. Britain went to have a seat at the table ofFriday summit.
