An 1,800-mile-long symbol of one of the world's most important geopolitical partnerships began delivering Russian gas to China today, the countries’ presidents announced.

By the numbers: The Power of Siberia pipeline is expected to “generate $400 billion for Russian state coffers” over three decades, per Reuters:

  • “The move cements China’s spot as Russia’s top export market and gives Russia a potentially enormous new market outside Europe. It also comes as Moscow is hoping to launch two other major energy projects — the Nord Steam 2 undersea Baltic gas pipeline to Germany and the TurkStream pipeline to Turkey and southern Europe.”
  • Vladimir Putin hailed it as “a genuinely historical event” on a video link with Xi Jinping, who emphasized the deepening ties between the countries.

My thought bubble: The pipeline could also be seen as a physical manifestation of Putin’s China strategy. He is squeezing everything he can out of a relationship that currently provides massive economic and strategic benefits, while putting off the question of what the increasingly unequal relationship across one of the world’s longest borders means for Russia.
