I am somewhat familiar with this. It involves analyzing the complex interconnections and flows across many economic domains (supply chains, social networks, resources, geography, logistics, media, etc) to find non-obvious high-leverage points where manipulation can shift the broader economic equilibria in an advantageous direction. Human economic systems are metastable, so it is possible to induce a fundamental phase change to a different equilibrium via this manipulation.

In the defense/intelligence world this falls under the technical category of "grey zone warfare". Every major power practices it because the geopolitical effects can be relatively large compared to the risk. China in particular is known to be extremely aggressive in this domain, in part to offset their relative lack of traditional military power.

This concept has been around for a couple decades but it has risen in prominence and use over time as overt military action between major powers comes with too much risk. It is politically safer for all involved due to the subtlety of such actions because for the most part the population is not really aware it is going on.
