The popular term in use is to say a multi-polar world. I say power block competition to emphasis that this is indeed an old pattern. In history it was competition between empires, kingdoms or nations. Think of European history in the c17, 18 and 19, now think of it on a world scale.
Examples;
"Brazil is blaming the problems with the supply of fertiliser not on Russia but on western sanctions, which were imposed without Brasília being consulted."
Rise in the price of staples "Egypt, with 100 million people, is scrambling to secure dwindling supplies, as are equally populous countries such as Bangladesh and Indonesia."
Both of these from a a review of The Age of the Strongman: How the Cult of the Leader Threatens Democracy Around the World by Gideon Rachman, Bodley Head
