Abstract:Eurasian Economic Union is an important institutional arrangement for regional integration. As a result of institutional design, Eurasian Economic Union is confronted with the challenges from a complex relationship between institutional legitimacy and effectiveness in the development course. This complex relationship not only restricts the development of Eurasian Economic Union, but alsoeffects behaviors of Eurasian Economic Union. China and Eurasian Economic Union member countries have formed “5 + 1” Mode (“Eurasian Economic Union + China”) and five separate “1 + 1” modes (“China + Members of Eurasian Economic Union”) in the practice of engagement with “The Belt and Union”. The “5 + 1” mode explores the construction paths from the economic and trade agreement to the free trade zone, while the “1 + 1” mode develops the construction paths from project cooperation to engagement of national development strategy. Both mode and path have laid a solid foundation for engagement of “The Belt and Union”.

Keywords:Eurasian Economic Union, institutional design, “The Belt and Union”, modes, paths
