I will connect from KE in T2 to CA in T3

I have a CJU-PEK-MNL routing on 02 Nov which will entail me to take KE879/CJU-PEK/1540 2725 and CA179/PEK-MNL/2000 0050+1.

I am a little concerned because KE and CA operate in different terminals. May I ask if:

1. The 2h 35m connection will be enough
2. Would you know if KE will be able to transfer my bag to CA
3. Is there a way to transfer airside? I saw signs in T3 before for transfers to T2 that do not seem to lead out to the bus shuttle service direction

Your help is highly appreciated

Thanks
