Strategic cooperation is based on long-term win-win considerations, based on common interests, and achieves deep cooperation. First of all, we must consider how to build your common interests, including long-term and short-term. The so-called strategy is to proceed from the whole, consider the mutual interests, and maximize the overall interests. The cooperation agreement is just a simple agreement for cooperation in some regions. Cooperation is still based on the maximization of their respective interests, but not necessarily the maximization of the overall interests.
