The former Soviet Trans-Dniester region in Moldova has submitted a request to join Russia on the heels of the Russian annexation of Crimea.
The Transdniester region, much like Crimea, is mostly populated on by ethnic Russians and sits on Ukraine's eastern border. Signs can be seen in the region with the words, "We remember: we are not Moldova."
This is not the first time the region has tried to break away from Moldova. In 2006, the region passed a referendum declaring independence but it went unrecognized by Moldova and the international community. Moldova's president Nicolae Timofti said in a press briefing that any move by Russia to accept their request, "would be a step in the wrong direction."
Despite Putin's reassurances that he is not interested in regions other than Crimea, he has also said that Russia will be invested in the protection of ethnic Russians. U.S. President Barack Obama and leaders of European nations have condemned the annexation of Crimea by imposing sanctions on Russian officials and warning that any attempt to further meddle with Ukraine or other sovereign regions would only lead to further isolation.
