The only way to break it is to demand that from Ming. What you should do is fully annex then release as vassal. If you don't want to fight Ming then you will need to become a tributary so he won't get called in.
Well, at this point, I have a far higher force limit than the Ming, as result of a far-flung empire from North America to Australia that I'm trying to build up to historical extent) and I did designed a triggered modifier aptly named "Ming Crisis" in my own mod to start somewhere in early 1600s that caused it to Ming to suffer (since I'm historically deterministic insofar as game goes

). The triggered modifier was actually intended to push towards Manchu rule over the China, coupled with events that caused Manchu rebels to spawn in all provinces with that culture, if Ming owned them. Basically, I wanted to see Qing replace the Ming as it have historically done.
But I'm generally reluctant to go to war with the Ming right now since I'm still consolidating the English control over the India but most of the subcontinent are now under either my direct control or my vassals. These vassals also received the "Princely States" triggered modifiers equivalent to what the March have, doubling the benefits when designated Marches which I do. Fortunately, my ally France (yes my ally as England, as strange as it may be

) just recently rivaled the Ming so that might be an interesting twist and perhaps pull the Second Opium Wars in there, heh.
Speaking of the historical extent.... is there a way I can gain control over the Egypt without need to wait on Imperialism CB to come up? It seems that I can't fabricate claims on Egypt perhaps because it was not considered overseas, unfortunately.
