2h transfer for international flights

Hi, I booked a flight from Tokyo HND to Paris CDG, with a transfer of 2 hours in Beijing Airport. It’s my first time traveling, is 2 hours enough ?

Also, I’m flying with Air China for both flights, but I can’t find information on checked luggage on their website for International to International.
Will my luggage be checked to my final destination (and so transferred on the connecting flight by Air China?) ? Or do I need to claim it during my transfer in Beijing to check it again?

I believe 2h wouldn’t be enough time if I have to claim luggage and check it again…
Thank you
