Once the spacecraft project was formally initiated, it was certain that the news would be made public to the entire world.
The decision by the higher-ups was also to make the spacecraft project public and to invite international institutions to participate in it, working together to raise funds for the project.
Leaving Earth is a matter for all of humanity.
It seemed somewhat counterproductive for the domestic market to make huge investments and go at it alone for the spacecraft project. Upon careful consideration, no matter how advanced technology became, it still required economic support; it would be better to hold onto the core technology and let everyone contribute together. As long as the core technology and leadership were in hand, there would be a steady stream of benefits, which could boost the economy and truly lead humanity out of Earth.
This general direction was certainly correct.
