Very interesting that the Chinese apparently felt bound to follow any treaty reached at this farcical aquatic display. I fully expected China to agree to anything to get the USA to dismantle what little industry we have left, and then thumb their noses at the world and simply not comply with the treaty.
In any event, this whole thing was a non-starter for them. They never had any intent to reduce their “carbon footprints.” They know it’s all a hoax.
I think five years ago China would have agreed to a deal in order to hoist us on our own petard. Now they’re worried about their investment, and they have to keep us upright.
