Fit ribs in the liner of anInstant Pot (or any electric pressure cooker). Add all ingredients except the Chinese BBQ sauce.
Set pot to cook at high pressure for 15 minutes (models differ with what they call things and settings, but the ribs should cook for 15 min at 15 psi). Let pressure reduce naturally.
Remove ribs from the pot, pat them dry then lather them with the BBQ sauce.
Grill on an outside BBQ or broil in the oven for about 5 minutes each side so sauce is bubbly and begins to caramelize.
