Abstract: The Building Blocks for the Development of International Framework on Space Resource Activities (Draft) has provided for the creation of priorities and resource rights, the assumption for the establishment of a safe zone for outer space resources activities and the institutional design for benefit sharing, which are quite different from the existing outer space law. The leading value orientation of the draft is to promote the efficiency of outer space resources activities. In the future, the international rules for the governance of outer space resources will be mainly based on fairness. Building an international management mechanism for space resources activities will be an important option.
