Most Europeans of the time considered the Chinese nothing more than a bunch of barbarians...
Besides, Switzerland is landlocked, how would this treaty even work?
As for artisans, how, even with sea access, would you send them all the way to Europe? Historically this could provoke the europeans.
The first statement is completely false. Most European powers recognized that they could bully the Qing on the coast; but even after they captured Peking in the Boxer Rebellion, when Cixi fled inland, the European powers couldn't pursue. The Europeans may have been racist, but they did not regard the Chinese as uncivilized barbarians. They regarded them as a technologically and culturally backwards, but still very organized, powerful group. Because they were.
Being landlocked doesn't matter. I don't understand why it would. Just because two countries don't share a border doesn't mean they can't have an embassy.
And they can get to Europe on fascinating inventions called boats. You can buy a ticket. Especially if you're a guest of a recognized government. Do you seriously think there were no Chinese people in Europe in 1861?
