There most certainly was a weariness of New World Wealth. In later decades, the Japanese tourists might have taken over the role just prior to the Chinese. However, I don't think there is much of a backlash against Chinese wealth as much there is a backlash against Chinese manners. I'm unprepared on much of Chinese history, being just a left-wing Italian Medievalist, so before starting I'd direct you to u/cthulhushrugged explanation of how Mao's cultural revolution rapidly destroyed a Chinese culture fundamentally incompatible with the rigors of the 20th century only to replace it with another, equally different culture which still influence China and the Chinese to this day.

Now, examples of Europeans disparaging new money are all over the place. In George Orwell's first published book, an account of the living and working conditions of the destitute in 1930's Paris and London called Down and Out, Orwell briefly spends time as a dishwasher in an unnamed expensive Parisian hotel near Place de la Concorde, this is what he has to say about the american guests:

"One morning on the fourth floor an American who was on diet wanted only salt and hot water for his breakfast. Valenti was furious. ‘Jesus Christ!’ he said, ‘what about my ten per cent? Ten per cent of salt and water!’ And he charged twenty-five francs for the breakfast. The customer paid without a murmur."

And again,

"I imagine that the customers at the Hôtel X were especially easy to swindle, for they were mostly Americans, with a sprinkling of English—no French—and seemed to know nothing whatever about good food. They would stuff themselves with disgusting American ‘cereals’, and eat marmalade at tea, and drink vermouth after dinner, and order a poulet à la reine at a hundred francs and then souse it in Worcester sauce. One customer, from Pittsburg, dined every night in his bedroom on grape-nuts, scrambled eggs and cocoa. Perhaps it hardly matters whether such o people are swindled or not."

This trope was so common Mark Twain played on it extensively in his 1869 travelogue, The Innocents Abroad where already in the title he defines he and his american travelling-companions as simple "Innocents." Funnily enough, it was one of Twain's best-selling works during his lifetime.

It's easy to form preconceived notions about new visitors. In Italy, the practice of stationing Carabinieri (the national gendarmerie) in towns far away from where they enlisted quickly led them to gaining a reputation for being bumbling oafs, mostly because they were as unfamiliar with local customs as new tourists would be today. Venetian dramatist Marco Paolini has a bit on Japanese Tourists in Venice he performed in the early 90's (he also briefly mentions them at the start of the video, before the bit) and it would seem that the latest "wave" of tourists comes from China, which according to some rankings, aren't always the worst perceived tourists.
