So, the international relations people said that the US should keep Russia and China apart. Instead, the anti RU sanctions and the likely anti China sanctions and possible future blockade drove them together to make each mostly sanctions proof.
There is some strange phrase like "earth island" or "center earth" that if allowed, would rule the world according to theory.

Regarding the landmass of Eurasia as the center of global power, Brzezinski sets out to formulate a Eurasian geostrategy for the United States. In particular, he writes that no Eurasian challenger should emerge that can dominate Eurasia and thus also challenge U.S. global pre-eminence.

China’s Xuanyuan Group Industrial Development plans to build a massive logistics hub in the Amur Region in Russia’s Far East, as freight turnover between the two countries has more than doubled over the past year, the group’s CEO, Hailong Xue, has told RT.
The project is one of several deals the Chinese industrial group has clinched with Russian investors on the sidelines of the Eastern Economic Forum in Vladivostok, and will offer equal opportunities for Russian and Chinese companies to participate in it.
The hub will be located between the city of Tongjiang in China’s Heilongjiang province and the town of Nizhneleninskoye and is designed to facilitate Russia-China cargo transfers.
“The location of this hub is very important as it will be right between our borders. There is a narrow stretch between our frontiers which makes cargo transfer rather problematic. But, with our project, we estimate that freight transportation will reach 10 million tons annually,” Hailong said. He expects cargo traffic between Russia and China to increase fourfold in the next few years.
Nizhneleninskoye
Nizhneleninskoye is a rural locality in Leninsky District of the Jewish Autonomous Oblast. Located on the Amur River, Nizhneleninskoye is the location for the Tongjiang-Nizhneleninskoye railway bridge which crosses over the river to China, joining it by a railway bridge to Tongjiang in Heilongjiang Province.Wikipedia
