MCT to transfer from T3 to T2, PEK, if I arrive in International fly and I have to take a Domestic Fly

Yes, there is free shuttle bus service available. By that, you can get to T2 in 10-15min from T3.

I have been looking in the next link in order to know the MCT from T3 to T2 for I - D transfers.

Certainly it is the information about Minimum Connection Time (MCT) of Transfer in T3
Minimum Connection Time (MCT) between T3 and T2
D — D: 120 minutes D — I: 160 minutes I — I: 120 minutes

But, what about the MCT from International to Domestic transfers ( I - D ) ?

Thank you very much for your help.

As I know, the MCT for transfer from international to domestic from T3 to T2 is 160min and the shuttle bus duration is 15min.
