This is a typical save face/buy time tactic of China.
What we know is Pakistan is not on the list, there're no mentioned that they is set to put Pakistan on that list in the memo also.
Pakistan need to work with the US in 3 months to block terrorist financing otherwise US will put her on that list, by some sources.
Only 3 parties opposed the US, Turkey have deep hatred to US recently , so no way to by pass it
KSA and China, if they openly oppose the US, the US will still has her way with her allies in EU, no matter what the outcome in FATF, so oppose her in every turn is very un-wise, this is the US we're talking about.
It's not quite clear who the US approach first, I think it may be KSA, if the KSA flipped, China alone is useless.
So, the logical conclusion is yield in , Pakistan is not on the list, is not on the memo , but Pakistan must work to satisfy the US concern.
If Pakistan can not do that, well, that's June problem, all parties can continue the fight in June, no way to put Pakistan on the grey list in June if China and KSA and Turkey "think" Pakistan is doing good enough, that's the whole point: "we agree that they MUST do more, but I think this is enough , you do not"
The US and her allies can call it a success, Pakistan avoid the bullet.
The US ensure Pakistan will work to satisfy her request in terrorist financing.
KSA and China get benefit.
This is a Win-Win solution, some may call it a bigger Win for China, China way of reap benefit during crisis is astounding.
Openly oppose the US is un-wise, especially when it come to terrorist.
My 5 cents
