While the “Belt and Road Initiatives” (“B & R”) has achieved fruitful results, it is also facing doubts and plight in moving forward. However, the active participation of international organizations in joint construction may provide a new path for the “B & R” to break through these obstacles. Although the involvement of international organizations in the construction of the “B & R” has achieved certain results, it is still in its infancy. The participation of international organizations from the system of the United Nations is relatively active, but important regional organizations and major international economic organizations are less involved. Some international organizations still have doubts about participating in the joint construction of the “B & R”. One of the reasons is that the connection between the “B & R” and the goals and purposes of international organizations is not very clear. Also, China’s influence in some international organizations needs to be improved. At the same time, the “B & R” is also facing external political pressure and internal problems. To break through the predicament of international organizations in coconstructing the “Belt and Road Initiatives”, it is necessary to deepen and widen publicity of the core values of the “B & R”. China needs to make full use of both existing cooperation mechanisms and new cooperation platforms in order to respond to questions from international organizations and the international community. Meanwhile, China should also constantly seek the point of convergence between the agenda of international organizations and the goals of the “Belt and Road Initiatives”, and implement cooperation projects between international organizations and the “B & R ” by improving the ability to set international agendas.
