Now, China in the 1700's was an economic and political juggernaught, not only had the Mughals finally been (once again) brought into line by chinese troops in the 1740's, the Chinese had also recieved news of the french, that had claimed the title of most splendid empire on earth, completely disregarding the Middle Kingdom. This did not sit well with the Son of Heaven, and thus he dispatched forces to invade the perfidious french: Taking the long and ardous trek from Shangai to the Austrian Netherlands, these reinforcements were sent to do: And to die, no matter the cost, no matter hte sacrifice, the french were going down.
Coinciding with severe revolts all over France (that among other things led to the liberation of Loisiana and Greece and the defection of several provinces to Austria and Spain) the ultimatum from the chinese overlords arrived: The ultimatum was as follows:
A Chinese overlord deliverign the Ultimatum to France
"Submit or die foolish humans!"
The french considered their options, then went for their muskets, unfortunately 150,000 chinese has a way of imposing their way of seeing things, combined with the dreadful revolts this made the french see reason, vassalization was after all preferable to death...
Now this was not the end of Chinese expansion in Europe, another invasion-fleet with more than 100,000 chinese had been en-route to France: Instead of landing in the newly-acquired province of Calais they set sail for England, the english war was if possible even shorter than the french one, the new technology of Leveé-en-masse made the chinese unbeatable, and after having assaulted their way from Cardiff to London the british government saw no other option than to surrender, becoming vassals of the chinese empire.
The british surrender to their new chinese overlords.
