With Joint US-South Korea military exercise planned for the near future, China has stepped in and warned the two nations not to go ahead with it. China claims that the joint military exercise in the Yellow Sea would be a threat Chinese security and also warned the US warships from being a target if they ever entered the Yellow Sea.
It is a bit awkward for China to be making such a statement when the US-South Korea has been doing such excercise numerous times in the past. Also when the exercise is to be held technically within South Korean waters. Why is China suddenly eager to be against this drill? It doesn't make sense. Maybe China is doing a favor for North Korea for something in return.
The Joint exercise's sole purpose is to keep peace in East Asia. It is also for suppressing North Korea for making any additional surprise attacks against the South.
China's interrupting of the peace keeping effort of US and South Korea is just simply wrong.

Why is China being against the US-South Korean joint military exercise?

1. Infringement of South Korean sovereignty
2. China just being a bully
3. Something related to North Korea
4. I have no idea

uhh... it's right at their backyard?

But it's not their front yard.
Tell them to take a hike.

Tell who to take a hike? And why?

The PRC/PLAN is not in favor of any demonstration of might by the USN. It doesn't matter if it is the Taiwan Straits in particular or the Yellow Sea in general. I guess it would be the same thing if some nation (not on the best of terms with the US or not from the western hemisphere) held a naval exercise in the Gulf of Mexico / Caribbean Sea.
President Obama sending more SSBNs to the western Pacific armed with Tomahawk Missiles is also displeasing the PLAN.

China take a hike.
It's not happening in Chinese territory.

Thanks for your balanced reply, AVON.

A Can of Man: I guess if the PLAN sent warships to have a joint exercise near mexico or cuba the US can't signal its displeasure, too? If they do, then people can tell them to take a hike too eh?

Pretty much.

Venezuala and others to include Russia have conducted joint excercises in the carib as long as they do not violate waters they are fine, matter of fact it's a good intel tool to analyze them.
