In recent years, US AI development has been primarily closed source, with models remaining proprietary (only the owners can see how it works, weights, etc) and the AI stack (chips, datacentres, software, etc) being limited to allies (e.g. Taiwan, the UAE, Saudi Arabia).

In contrast, Chinese AI development has been primarily open source, with models being exported around the world.

Carbon border adjustment mechanisms (e.g. the EU's CBAM, which entered into force in January 2026) place fees on imports according to their carbon emissions such that foreign producers face a similar carbon cost to domestic producers subject to carbon pricing.

For example, if the EU has a carbon price of €70/ton (meaning that producers must pay €70 for each ton of carbon emitted) and India has a carbon price of €0/ton, then Indian exports to the EU will be charged 70-0=€70 per ton of carbon emitted.

Friend-shoring is the practice of shifting supply chains and production to countries that are politically and economically aligned or considered reliable allies, rather than the lowest-cost (or geographically closest) producers.
