/kloc-in the 0/8th century, the so-called "Peter the Great's Will" was circulated in Russia and Europe, which proposed that Russia would expand to the four oceans and gain access to the sea, thus controlling the whole of Europe. Since then, Russian expansion of Zhang Zhilu has proceeded in this direction.
During yekaterina's period, Russia realized the coveted northern shore of the Black Sea, annexed the Crimean Khanate, gained the right of passage in the Turkish Strait, and finally got the sea port of the Black Sea.
Around 1650, Russia relied on Cossack cavalry to open the way and quickly occupied the northern part of Asia and the Bering Strait in the east. Later, he used two Opium Wars to blackmail the Qing government, cut off 654.38+0.5 million square kilometers of land in China and bought Vladivostok, a port in the Pacific Ocean. But the port was frozen for half a year, so Russia leased Lushun and Dalian after the Sino-Japanese War.
/kloc-In the middle and late 20th century, Russia marched into Central Asia, successively eliminated the khanates in Central Asia, and demarcated its sphere of influence in Afghanistan, Iran and Britain. Until the 1970s, the Soviet Union invaded Afghanistan, which opened the last effort to compete for the Indian Ocean. But in the end, the Soviet Union was dragged into the imperial cemetery and eventually disintegrated.
Therefore, Russia has been seeking sea ports from the four oceans, but the effect has been poor, not that there is no sea port, but that there is no excellent sea port.
