Does the Guangxi project manager have to be the consortium leader?

Not necessarily.

The Guangxi project manager is not necessarily the consortium leader, but is appointed by the consortium leader. If the leader in the consortium does not have construction qualifications and is only responsible for project financing, and a member of the consortium has engineering construction qualifications and is responsible for project construction, the project manager should be assigned by the consortium members.

The leader of the consortium is the representative of one of the companies that forms the consortium and participates in the bidding, and can represent the consortium.
