EU and Russia battle for influence in Balkan region

'Investing in the stability and prosperity of the western Balkans means investing in the security and future of our union'

For years, Russia has worked to gain influence in south-east Europe, using Serbia as a foothold to establish a friendly pocket on a hostile continent.

The European Union finally is pushing back. Jean-Claude Juncker, the European Commission president, is embarking on a seven-nation Balkans tour on Sunday to promote the EU's new eastward expansion strategy.

Russia mainly wants to discourage the Western Balkan countries – Albania, Bosnia, Macedonia, Montenegro, Kosovo and Serbia – from joining Nato. But Moscow is also trying to deter them from joining the EU.

The EU sees the prospect of membership as an incentive for reform in the volatile Balkans region, which was torn apart by war in the 1990s. Its expansion strategy puts Serbia and Montenegro in position to join should the bloc open its doors to more members, tentatively by 2025.

Serbia is a major target of Moscow's anti-Western activities in Europe because the two Slavic and predominantly eastern Orthodox Christian nations share deep cultural and historical ties.

The Kremlin is so concerned about losing its ally that the Russian foreign minister, Sergey Lavrov, repeatedly argued, while in Serbia last week that EU membership isn't all it is cut out to be.

Mr Lavrov also gave a warning; the EU's repeated calls for Serbia to align its foreign policies with the bloc as a precursor to membership and to impose sanctions on Russia, he said, are the same "mistake" the West made by pressuring war-torn Ukraine to choose between it and Russia.

Bosko Jaksic, a Serbian political analyst, thinks the "Russians are getting increasingly nervous as they lose allies one by one in the Balkans".

"It's not clear how far they are willing to go to preserve their interests here, but judging from what they did in Ukraine, they are willing to go far," Mr Jaksic said, referring to Russia's annexation of Crimea and support for pro-Russian rebels in eastern Ukraine.

Mr Lavrov also said that "Europe is facing an unhealthy situation" because of Nato's eastward expansion. Montenegro joined the Western military organisation last year despite Moscow's strong opposition. He praised Belgrade for maintaining military neutrality and refusing to join Nato.

"We are convinced that this status is one of the main factors ensuring stability in the Balkans and the European continent in general," Mr Lavrov said.

There have been mounting fears in the West that Russia is using Serbia to foment tensions in the Balkans by arming its ally with warplanes and tanks, while working to destabilise neighbouring Bosnia, Montenegro and Macedonia.

The EU's foreign and security policies grew out of Europe's failure to respond to the wars in the Balkans that accompanied the breakup of Yugoslavia. The bloc remains wary that some of the ethnic cleavages that sparked the conflicts of the 1990s persist.

Three countries have become EU members: Bulgaria and Romania in 2007 and Croatia in 2013. The rest either are candidates for membership of potential candidates.

"Investing in the stability and prosperity of the western Balkans means investing in the security and future of our union," Mr Juncker said ahead of the trip.

Mr Juncker's tour of the Balkans, which starts in Macedonia on Sunday and ends with an EU summit in Bulgaria on 1 March, is seen as the EU's belated attempt to counter Russia's reach.

"Paradoxically, the Russians and their policies in the Balkans have triggered alarm bells that woke up the European Union into action," Mr Jaksic, the analyst, said.
