As a counterweight to the European Union, Russia’s Vladimir Putin is pursuing an ambitious dream rooted in memories of Soviet glory: the Eurasian Union.

It’s a strategy to pull former Soviet satellite states back into Moscow’s orbit through a combination of incentives and threats. And embattled Ukraine, a huge country of 46 million people, is at the center of the game plan.

Putin has put the Eurasian Union at the top of his presidential agenda, voicing hope that the new grouping could become a major economic powerhouse on par with the EU.

Here is a look at how Russia has fared in bringing other former Soviet neighbors under its thumb:

IN PUTIN’S POCKET

Putin understands that it’s not just military might that matters in winning allies. Cash counts, too.

He formed an economic bloc with Belarus and Kazakhstan in 2010 with a goal to bolster mutual trade through the removal of customs barriers. Armenia and Kyrgyzstan also want to join, and Tajikistan could be on membership track, too.

This Customs Union is the basis for the Eurasian Union, a more ambitious economic bloc set to be formed in 2015.

Belarus, led by authoritarian President Alexander Lukashenko — dubbed "Europe's last dictator" — has been Russia's closest ally.

Kazakhstan, led by autocratic President Nursultan Nazarbayev, is the second largest country by territory and economy among the ex-Soviet nations. Nazarbayev has maneuvered between Russia and the West. But Russia has little leverage over Kazakhstan, whose energy riches and booming economy make it nearly an equal partner.

Armenia, whose economy has been crippled by a blockade imposed by arch-enemy Turkey, has been a staunch Russian ally.

Kyrgyzstan, an impoverished Central Asian nation rocked by political instability, hosted a U.S. air base key for supporting operations in nearby Afghanistan. The base is now being shut down under Russian pressure.

Tajikistan, one of the poorest ex-Soviet nations on Afghanistan's northern frontier, hosts an estimated 5,000 Russian troops and depends on Russian economic aid and remittances from migrants working in Russia.

WESTWARD GAZE

Some ex-Soviet nations have developed strong ties with the West and shed Russia’s influence.

Energy-rich Azerbaijan has been shipping its Caspian oil to Western markets via a pipeline bypassing Russia and stayed away from any Russian integration projects. At the same time, it has maintained friendly ties with Russia, where some of its richest tycoons have major assets.

Georgia built strong ties with the West under U.S.-allied former President Mikhail Saakashvili, who sought to restore control over Moscow-backed breakaway provinces, triggering the 2008 Russia-Georgia war. Saakashvili's party lost control to a coalition led by a billionaire tycoon, who made his fortune in Russia and moved to normalize ties with Moscow. Despite Georgia's ongoing rapprochement with Russia, political ties have remained frozen over Moscow's recognition of independence of Georgia's separatist provinces after the war.

Impoverished Moldova, located between Ukraine and Romania, has sought to build closer ties with the West and faced Russian trade sanctions.

SITTING ON THE FENCE

Resource-rich Uzbekistan, led by authoritarian President Islam Karimov, who has been in office for more than two decades, has aspired for regional domination and zigzagged between Russia and the West.

Turkmenistan, a desert nation sitting on huge natural gas reserves, is ruled by authoritarian President Gurbanguli Berdymukhamedov. It has stayed away from Russia-dominated alliances and sought to develop close energy ties with both the West and China.
