A lot of Bible scholars do use Russia .. but some also include China and all the Arabic nations.
When GOD puts the “hook in the jaw” to draw Gog and Magog DOWN, it doesn’t give any real clue as to who the exact nations are that will be tricked into the Valley of Megiddo (in Israel), in the site of Mt. Carmel; where they will be destroyed.
I’ve personally never heard the China thing myself.
