Think Progress offers an explanation for the ugly mess going on in the Ukraine.
The protests began on November 22, after President Viktor Yanukovych reversed course and refused to sign political and trade agreements with the European Union that had been in the works for years after heavy pressure from Moscow to abandon the agreements. Despite a violent police crackdown, protesters vowed to continue blockading streets and occupying public buildings until their central demand is met: the current government, including Yanukovych, must go.
The treaties would have opened the European Union market to Ukrainian companies and could have boosted the Ukrainian GDP by more than six percent over ten years. The country is suffering through an economic depression and lower tariffs and expanded competition could have also lowered prices, “fueling an increase of household consumption of some 12 percent.” Ukraine would have also adopted 350 EU laws, codifying what many Ukrainians saw as a “commitment to European standards of governance and social justice.” To them, the treaty was a way of diminishing Russia’s long-time influence and reversing the trend of persistent economic corruption and sluggishness.
