Would you agree on a pre-emptive strike against North Korea?

No, China would object. NK gotta do something stupid enough to make China abandon it.

North Korea is Chinas only ally in that area

I consider the opposite to be closer to the truth: China is North Korea's only ally in the area. China values its economic relationships with South Korea, Japan, and the US, relationships more lucrative than the one it has with the heavily-sanctioned North Korea.

US is buddy buddy with Japan and South Korea, China will never abandon NK unless they did a direct strike on US mainland.

I can see China staging a land invasion of North Korea for the sake of maintaining a buffer zone between itself and US-ally South Korea. This is if North Korea were to attack the US or a US ally.
