Re - China
It's not a clamp down per se.
It's economic circumstances, and many (smaller) bars can't get discount links, so they sit out or buy much lower quantities. (G)I-DLE are coming back and 3 of their bars couldn't get discount links so aren't participating in the pre-order through their bar.
Only 2 bars I know have have boycotted - Karina Bar and Yuqi Bar. For Itzy, a confluence of events, including their general popular decline., but economic circumstances would have contributed. That said, I wasn't aware Itzy was overly huge in China, my impression they don't have much of their proportion of sales from the Chinese Market
Europe and U.S. sales were NOT released yet. Also JYPE is slowly sending out the shipments. It will rise higher next month.
I've seen this said often, but I think there's a huge misunderstanding.
Yes, the US release is delayed - this is the domestic US distribution. Example rocking up to Walmart or Target in the US and buying an Itzy album off the shelf.
People oversease ordering Itzy albums from Korean sellers (ie Ktown4u, Makestar etc) are perfectly fine. Furthermore, the sales listed in the thread are Hanteo sales, which rarely count for domestic distribution US/EU sales anyway (and certainly not anywhere near the gap of 500k)
The long term discrepancy between Hanteo and Circle for Itzy (and many JYP groups) is their Hanteo sales are the Korean (or Korean distrubtion based) retail sales, whereas the Circle is their stock shipment, including stock shipments to other Countries for erstwhile domestic distribution in that country. So their Sneakers album sold 600k Hanteo but 1 million Circle - because the 1 million circle includes the US/EU shipments for domestic sales (which would be counted retail as Billboard for US and the respective countries for EU).
So people going on about how US for Itzy is delayed is true - but that has no affect on Hanteo sales. Those US sales will be Billboard focused.
