I'd rate the Chinese thermobaric as between the American MOAB and FOAB. Might be fun to call it "Mistress of all Bombs" or something silly like that. The capacity of the H-6K is about 9,000 kg, but if you look at the Russian FOAB, the Russian FOAB is apparently more efficient than the American MOAB, suggesting different bomb designs. If you assume the Chinese use similar technologies, the bomb would weigh less than the MOAB, but be around the same power or be more powerful. But since the FOAB is heavier than the likely size of the Chinese MioAB, the Chinese version should be somewhat less powerful.
