I have a 1 hr layover at Beijing Capital Airport between connecting flights on Air China.

I will arrive from Hong Kong to Beijing on Air China flight CA112 at 17:30 and then have a connecting flight on Air China flight to Sheremetyevo CA881 at 0630 with check-in bag and hand-carry.

I'm concerned it will not be enough time to make my flight. Is this sufficient time or do I have options to make sure I don't miss my connecting flight?
