Which BRICS country has the strongest comprehensive strength?

There is no doubt that China, the closest to China is Russian. 1. Both of them have large land areas, and Russia has the upper hand. In terms of heavy industry, Russia has a better foundation than us, but our country has more advantages. In light industry, Russia is a big importer, but China is different. In terms of land use, Russia's North Asia has only left it with resources and territorial advantages. The climate in North Asia is appalling, except for the railways in transportation. Militarily, each has its own merits, and no one can beat anyone. But when it comes to fighting, China people are not the kind of people who fight one on one. Economically, China's industrial structure is relatively perfect, and Russian large machinery is also outstanding in the world, but it is not as good as China's.
