Who imitated the Chinese style in his Le Chinois galant?

The person who imitated the Chinese style in his "Le Chinois galant" was François Couperin.

This musical work, a suite for harpsichord, was composed in 1717 and is a prime example of European composers experimenting with the musical trends coming from the Far East.

Couperin's work features elements like the use of pentatonic scales, the inclusion of exotic instruments like the lute and the mandolin, and a general mood of whimsy and lightheartedness that was often associated with Chinese music at the time.
