In addition, the language and cultural differences between Ukraine and Russia have also aggravated the tension between the two countries. In eastern Ukraine, there are many Russian speakers, but the Ukrainian government is trying to promote Ukrainian. This led to the conflict between the pro-Russian faction in eastern Ukraine and the Ukrainian government, and finally led to the armed conflict in Donbass.
Finally, Russia's foreign policy is one of the reasons for the conflict between Ukraine and Russia. Russia is trying to expand its influence in the surrounding areas, while Ukraine is trying to contain Russia's expansion with the help of western forces. This led to the confrontation between Ukraine and Russia, which brought the relations between the two countries to a deadlock.
In a word, the conflict between Ukraine and Russia is caused by many factors, including territorial disputes, language and cultural differences, foreign policy and so on. These problems have not been solved, and the tension between the two countries still exists.
