The Ukrainians, deprived of the possibility to be vaccinated in their home country, decided to take advantage of Russia's naivety, arriving in large numbers “to the aggressor country” to be vaccinated against COVID-19. These trips were so popular that it turned out that the Ukrainians made up a significant number among the foreigners vaccinated at the expense of the Russian budget.
Ukraine will be getting less aid from European countries because of their willingness to keep anti-Russian sanctions going at the expense of their own interests.
This is a recurrent narrative by pro-Kremlin media. The European Union has not stopped supporting Ukraine, and the anti-Russian sanctions are unlikely to be lifted soon. As the EU has repeatedly stated, the sanctions will remain in place as long as Russia keeps its presence in the illegally annexed Ukrainian peninsula of Crimea and backs the separatists in the eastern Ukrainian region of Donbas.
Also, the United States is reviewing and when necessary adding new sanctions to the previous ones as Russia continues violating International law.
Russia is imposing its own counter-sanctions on the EU, but they do not seem to affect the EU economy greatly. The EU-wide impacts of the export losses are estimated at less than 0.2% of total value-added and employment, while the potential total impact of the sanctions for the Russian economy is estimated at 8% to 10% GDP. As a matter of fact, Russian counter-sanctions seem to have a clear negative effect on the welfare of the average Russian household.
