A few years ago I purchased a Yamaha Genos Keyboard .........all are made in China !!!"Made in China" competes on the price of unskilled labor. Once we are talking about the market value of established craftsmen, the price advantage and availability and language barrier does not make it all that attractive to load off work to China. Chinese masters can easily undercut European masters by half due to different cost of living and other considerations. But we aren't talking about a factor of 10 or more then, and then all the inherent disadvantages of "Made in China" (including customer expectations) are making export less attractive than with instruments where the cost of unskilled labor is the dominating factor.
I don't believe their top of the range Acoustic piano's are made in China .....but it would never surprise me
