Steep climb for them. Good luck
Its the world vs china on advance packaging as almost everyone that is a maker in this space is part of the UCIe consortium

So, this is interesting... In the short-term, perhaps the motivation is to have something that's more cost-effective to deploy on older nodes.

If we wind the clock forward a several years, it could serve as in impediment to the inter-operation and inter-working between (i.e. Chinese and Western-designed) chiplets, that is the core mission of UCIe. Ultimately, it puts us on the track of fragmentation and a schism in the chiplet market. Along with some external leverage, this can work against UCIe-based designs and turn support for that standard into a competitive liability.

The China Chiplet league! Is the Marvel or DC?

So true. China is big enough to flip the UCIe on its head down the road.

It could happen. The camel's nose under the tent will be when western companies start making chiplets, or at least special versions, with some future revision of ACC. That will be needed, if you want to sell your chiplets into the future Chinese ecosystem. Once enough western chiplets have ACC versions, then you could see ACC chiplets being adopted by western customers, as it would enable them to use some lower-cost Chinese chiplets.

Or, ACC could just die out. Maybe things smooth over with China, one way or another, and they begin to embrace UCIe as they move onto newer process nodes where it's viable.
