This slows Japan for 2 turns, but ultimately opens the door for Japan’s easier conquest of Asia. USSR, too, because you lose your mid-size blocking/countering force(usually stacked in Yak) by the “USSR takes Man” move.
You might look through these fora(Axis & Allies) and the Player Help fora for ideas. Look for UK IC in India, US IC in Sinkiang, and USSR/Russia’s best/first turn/move. (Whew!!)
and see what you can come up with to counter the J1 & J2 (China) moves.
Remember, you, or you and your Allies have to work together in 1-2 or 1-2-3 fashion to defeat the Axis.
