We discussed before, mainland was the last major country in Asia to open up. By then, most people had already done their résas and committed to other destinations. Plus, with the Yen at historic lows against major currencies, it's not surprising whereas I believe the central bank of mainland China deliberately keeps the RMB at a stable float against other currencies (I think it's been 1 EUR = 7,8 RMB for months and months now).
