Regardless of tariffs, why are western vendors increasing puer prices the last few years?

I keep waiting for there to be no price increases. Since 2021 the US dollar has strengthened about 11% vs the Yuan which should make it 11% cheaper for Americans to buy. Over the last two years China reported CPI has been close to flat (almost no goods inflation) and PPI (manufacturing costs) have been negative so labor and non-leaf materials should be flattish. China has essentially been in a recession the last two years and real estate prices have been falling so I can't imagine storage expenses going up and local demand is probably weaker. Interest rates have fallen over the past year so inventory financing costs should be lower. Am I missing something?
