This meeting was not greatly related to Zhao Yi, as he was only aware of the final outcome—
the agreement to allow foreign institutions to participate.
Exactly how foreign institutions would be involved required a series of subsequent discussions and communications with the relevant foreign agencies.
Zhao Yi was not surprised by the outcome, primarily because the spacecraft project was simply too enormous, with related funding easily reaching tens or even hundreds of billions, making the expenditure on the project alone incredibly vast.
Economic considerations were only one aspect.
On the other hand, there were issues of construction time and technology—the spacecraft project was not just about three core technologies, but involved all aspects of technology.
Whether it was electronics, biology, materials science, etc., many high-end technologies in various fields were not yet available domestically.
Take materials, for example.
