China holds a 87–13 advantage over Saudi Arabia on the Relative Advantage Index, a decisive margin.
The margin is driven by military spending (80% of the combined total, $336bn) and economic size (GDP) (94% of the combined total, $18.7tn).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side. Those factors are excluded and the remaining weights renormalised, never substituted.
