EU foreign ministers on Monday failed to agree sanctions over the political crisis in Belarus, despite a plea for support from opposition leader Svetlana Tikhanovskaya. The former Soviet republic has been convulsed by unprecedented demonstrations against President Alexander Lukashenko since he was returned to power in a disputed August 9 election and launched a brutal crackdown. Tikhanovskaya met EU foreign ministers in Brussels and urged them to sanction Lukashenko but, despite repeated statements condemning the veteran strongman and warning of measures, after more than six weeks the bloc has still yet to act. Cyprus, which has good relations with Lukashenko's key supporter Russia, has blocked EU agreement on measures against Belarus, insisting that sanctions against Turkey over a maritime gas drilling dispute must be agreed at the same time. "Although there is a clear will to adopt these sanctions, it has not been possible to do that today because the required unanimity was not reached," EU diplomatic chief Josep Borrell told reporters after hosting the talks. Nicosia's position has support from some EU countries but the patience of others is wearing thin, with Latvian Foreign Minister Edgars Rinkevics lashing out on Twitter. "It is regrettable that today we could not decide on sanctions on violations of human rights there due to 'a hostage taking' by a member state. Sends a wrong signal to Belarusians, our societies and the whole world," he wrote. Cypriot foreign minister Nikos Christodoulides defended his country's stance, insisting the EU must have a coherent response to violations of sovereignty and human rights. "Our reaction to any kind of violation of our core basic values and principles, cannot be a la carte. It needs to be consistent," he said. The matter will now be considered by EU leaders at a summit in Brussels on Thursday and Friday, and Borrell said he wanted the sanctions signed off before the next meeting of foreign ministers in October, warning that "the credibililty of the European Union" depended on it. After meeting the EU ministers, Tikhanovskaya told reporters that sanctions were a key tool to "force the so-called authorities to start dialogue with us". "I think leaders have reasons not to push for these sanctions but at this meeting I asked just to be more brave in their decisions," she said. The EU and other Western powers have rejected the result of the election, saying the poll was not free and fair, and Brussels has drawn up a list of around 40 members of Lukashenko's regime to hit with asset freezes and travel bans. "We must also address the question of whether Mr Lukashenko, who is the main responsible, should not also be sanctioned by the European Union," Germany's Foreign Minister Heiko Maas said. The strongman, who has ruled Belarus for more than a quarter of a century, has responded to the protests with a security clampdown and turned to his longstanding ally Russia for help. Tikhanovskaya, who fled to Lithuania for her own safety after the election, backed sanctions on Lukashenko himself, saying "of course I think it is necessary". And she urged the EU to make a formal call for new elections -- something it has so far held off from, despite rejecting the August 9 poll as illegitimate. In the latest protests against Lukashenko, tens of thousands defied a heavy security presence to march in the streets of Minsk on Sunday, with authorities saying they detained more than 440 people. The EU is also considering what finance could be given to civil society in Belarus, after Poland called for a billion-euro stabilisation fund to help the country. Tikhanovskaya warned care must be taken to ensure the money does not end up in Lukashenko's coffers, effectively funding him to carry out further repression. Tikhanovskaya's meeting with EU ministers, followed by an appearance at the European Parliament, was part of her effort to maintain international pressure on Lukashenko as he clings to power. bur-pdw/dc/jj
