Let's clear things up: back in this context means support. I don't see any country backing Bitcoin because there's no way to control it anyway. Some people love throwing in China numbers, but a quick research would tell you that taking control is far more complicated than that.
Ripple could absolutely be backed though, considering they're a central entity. This article is a reach though lmfao. It just assumes that China is in control of Bitcoin and that the US can counteract that by supporting Ripple. Garbage lmao.
