Last month I read Ukraine Update June 14, which begins:

Russia has de-dollarized, and the yuan will now be the main trading currency for Russian citizens. China’s takeover is nearing completion.

This remined me of Robert Heinlein’s novel Sixth Column (originally serialized in 1941, first published in book form in 1949). Near the beginning:

…China was a big bit even for Soviet Russia to digest…. we [the USA] had our backs turned when China digested Russia ….

From the Wikipedia entry for the novel:

The idea for the story of Sixth Column was proposed by John W. Campbell, who had written a similar unpublished story called “All” (it would eventually be published in the anthology The Space Beyond). Heinlein would later write that he “had to reslant it to remove racist aspects of the original story line” and he would also have to write that he did not “consider it to be an artistic success.

The novel still has a lot of racism and is quite hard to take with modern sensibilities. I hate to think of what Campbell’s original version was like.
