1, economically. The fundamental problem in Ukraine lies in the economy. One of the western countries has an economy similar to that of Vietnam. Shanghai's GDP is almost equivalent to two Ukrainians! The population of Shanghai is only half that of Ukraine. It is only natural that such a country does not make progress and engages in politics every day. Russia sells resources, and its GDP also reaches $654.38 +0.4 million. Ukraine is awesome, better than Russia. Now it is attached to Europe and America, and its GDP is only $3,700, less than a fraction of that of Russia.

2. diplomatically. Mongolia, like Ukraine, is sandwiched between great powers. It develops equidistant diplomacy, relying on China in economy, Russian in security and Japanese in technology, thus ensuring its own security. Ukraine should be like this, but it is close to Russia for a while and Europe and America for a while. As a result, neither side benefited. In particular, Ukraine's accession to NATO is a taboo for Russia. If Mongolia wants to join NATO, China will arrive first.

3. politically. Its oligarchy. This is not decided by the people. In particular, the United States threatened to talk about the asset seizure of European and American oligarchs. The oligarchs immediately turned against Russia, angering Putin. Cause this difficulty.
