Hey! Yes, every border of China and/or Russia should be here. I have deleted the quiz and will submit it soon after the major edits. If it happens that the China/Russia borders plague the idea and presence of the other countries that make it difficult, then I won't submit it again. Thanks for pointing the out that flaw!
