Well, they're a year ahead of schedule...
The official figures for 2017 came in at $84.07 billion.
They did more than $8.1 billion in business in December alone. With the opening of the new ESPO oil pipeline connecting Siberia to China doubling the amount of oil China can import to 600,000 barrels per day we'll see those numbers continue to accelerate.
And that's the key. Remember, the massive $400 billion gas deal China made with Gazprom in 2014 hasn't begun delivering gas. The first Power of Siberia pipeline isn't due to be completed until 2019. The second Power of Siberia pipeline is on the table after this one.
And the two countries just agreed to a third pipeline to bring gas in from Russia's far east last month.
So, despite back-biting from western media about the profitability of these projects, they are going forward and the two countries continue to strengthen fundamental ties to one another.
