After they ban all of the direct, existing investments in Israel, then yes, that would be a next move I would support. Hell, if they just sold (or threatened to sell) a large portion of the US Treasury bonds they hold, I imagine China could really put the screws on both imperialist, settler-colonial projects.

I am not knowledgeable enough to know what the full ripple effects of such a sell off would be, but I imagine China would prefer to coordinate something like that (or wide-reaching sanctions) with other countries, rather than moving unilaterally. But Ra knows the US deserves to be sanctioned into the ground for their actions on the international stage.
