Brazil undertook a similar project and moved the capital from Rio de Janeiro to Brasilia in 1960.
This was a big mistake.
Brasilia is like giant robot very far away from the people and with no connection with society. Brasilia has the highest income per capita in Brazil and it doesn't produce anything.
Rio Janeiro, the old capital, was left with no alternative and has been decaying ever since.
"Dort wo man Bücher verbrennt,
verbrennt man auch am Ende Menschen."
- Wherever they burn books, in the end will also burn human beings.
Heinrich Heine
