on 24 April 1997 with the signing of the `Treaty on Union between Belarus and Russia`, who were changed in name in the Union by Belarus and Russia.  Several other agreements were signed on 25 December 1998 to strengthen political, economic and social integration.  The two leaders also met in December 2019, but failed to reach an agreement, although street protests against integration erupted in Minsk, highlighting internal political skepticism towards it. Under the Agreement, third-country nationals holding a valid visa from Russia or Belarus may enter, travel to and stay in the other country until their visa expires to cross the land border of Russia and Belarus by train or air and by the main motorways. Each party reserves the right to refuse entry to such persons or to reduce their stay in their territory. Two decades after Russia and Belarus signed an EU treaty to deepen integration, the two countries continue to debate the terms of the agreement without much success. The latest breakthrough took place at the beginning of February, with the visit of Belarusian President Alexander Lukashenko to Sochi to discuss with Russian President Vladimir Putin the process of integration into the Union. However, the head of the Russian government did not announce the nature of the agreements and specific decisions. He stressed that Russia has an interest in taking cooperation with Belarus to the next stage, filling it with content, using the best practices of Russia and Belarus and implementing them in the framework of sectoral interaction.
