Fundamentally for China or for The Belt and Road（B＆R）countries，the implementation of B＆R is not solely a question of pure economics，but instead is a semi-economic issue with elements of “culture over capital”and “institutions over technology”.In contrast to capital or technology，“institutional-cultural”constraints are fundamental constraints that count both the most flexible and inflexible of them among their number.We define “institutional-cultural”constraints as the mutual recognitions and obstacles within internal institutional arrangements that stem from cultural elements，such as custom or values.It also concerns the impact of these differing internal institutional arrangements on the internal dynamics of the broader region or community，the establishment of formal institutional arrangements and the creation of institutional environments.The key to bridging institutional-cultural constraints is to establish a shared institutional-cultural cognitive system that is mutually-respecting，mutually-tolerating and workable，on top of a foundation of mutual prosperity.The consideration and implementation of such a project，no matter from a logical or practical perspective，is the first step in the effective implementation of B＆R.
