1. Describe the problem

The conflict between Russia and Ukraine was caused by the coup in Ukraine, the oppression of pro-Russian areas and the Chernobyl nuclear accident, and eventually evolved into an armed conflict based on national security, territorial sovereignty and political interests.

2. Ukrainian coup and oppression of pro-Russian areas

20 14 Ukrainian President Yanukovych was forced to resign due to opposition demonstrations during his administration. Since then, the new Ukrainian government has promoted the process of EU integration and established closer relations with western countries, which is regarded as a challenge to Russian interests. In this context, the Crimean peninsula was annexed by Russia in the same year, which triggered widespread condemnation from the international community.

In addition, the Ukrainian government also took actions to suppress local pro-Russian elements, including launching military operations and implementing economic blockades in Donetsk and Lugansk, which caused dissatisfaction and anger among local people and Russia.

3. Chernobyl nuclear accident

The Chernobyl nuclear accident was a major nuclear accident at the Chernobyl nuclear power plant in Ukraine from 65438 to 0986, which caused serious radiation pollution and a large number of deaths. This incident has a far-reaching impact, which not only brings serious consequences to the people of neighboring countries, but also lays a hidden danger for Russia-Ukraine relations.

4. Armed conflict

The interaction of the above factors led to many conflicts between Russia and Ukraine, including Russia's annexation of Crimea in 20 14 and the declaration of autonomy in eastern Ukraine. From 20 14, a series of armed conflicts broke out between the two sides in Donbass area, resulting in thousands of deaths and millions of people leaving their homes.

Although the international community has repeatedly asked the two sides to cease fire and resolve their differences, the tension between Russia and Ukraine has continued to this day and has become an important issue in the international political structure.
