First, Russia is waiting for a lower exchange rate. The debt of 450 million yuan is not a small sum, but also a huge sum for Russia, because Russia's GDP is only a little more than that of a province in Guangdong Province. What kind of concept is this? A big country with the largest land area in Asia, a country with military strength that can compete with the United States, has only such a small GDP. Therefore, for Russia's current domestic economic conditions and arrears, we need to wait for a low exchange rate to repay the loan, because the interest and money will be less, which can of course save a lot of money and reduce some domestic pressures and burdens for Russia.

Second, Russia's domestic economy has experienced great turmoil. Everyone is familiar with the three reformers in the Soviet era, Khrushchev, Borzhnev and Gorbachev. These three famous reformers experienced great fluctuations in the recovery and construction of domestic economy. Among them, Sino-Soviet relations were friendly in Khrushchev's era, but his reform failed to cheer up the Soviet economy. Finally, Gorbachev's reform led to the disintegration of the Soviet Union. This has caused great economic pressure and recovery difficulty for Russia after the disintegration of the Soviet Union. Screw country has a long-term economic crisis, and its people live in poverty, not to mention 450 million. Of course, at that time, the IOUs played by the Soviet Union and China did not really lend 450 million Swiss francs, but were delivered to the Soviet Union in kind and IOUs written by the Soviet Union.

Finally, Sino-Russian relations have developed steadily. For this debt, after the founding of Russia, Sino-Russian relations began to normalize and gradually consolidate, but at that time, China's domestic economy was busy, and China didn't really need this debt. However, if China asks Russia for this debt at this time, it will lead to bad Sino-Russian relations, because this debt can be said to be worse for Russia, so this debt can be regarded as the foreshadowing of our trust and relationship with Russia, and it doesn't matter how long it can be returned as Russia.
