PRAGUE (AP) — Amid Ukraine's deepening crisis, the presidents of post-Soviet republics and EU member states are gathering in Prague to save a project to boost their ties. Launched in the Czech capital in 2009, the Eastern Partnership was supposed to inspire democratic change in six post-communist nations to ensure political stability and turn the territory east of the EU's border into a region of stable and prosperous democracies. In exchange, the European Union promised Armenia, Azerbaijan, Belarus, Georgia, Moldova and Ukraine free-trade agreements, visa-free travel and other incentives.
