(Thanks to @Sea_Gull for bringing this map to my attention!)
Edit: Since this used Google data, China is notably missing here, but if a commenter on a random Nintendo fan site covering this is to be believed:

China stay winning.
Russia and Ukraine should lay down their arms and embrace their shared love of Mew.
