China likes that yapping little chihuahua because it keeps the US controlled South Korea away from it's borders. They know if little Kimmy ever uses these things he will cease to exist, and China's fence goes away. Keep in mind, when there is stability and economic prosperity old enemies tend to get friendly. North and South Korea might get chummy and that also brings the fence down, so China will allow that nincompoop to continue his reign of doltishness.
