Joining the market is the strictly dominant strategy for any organization from the results. The Nash equilibrium shows that, regardless of the organizations that have already existed in the market, joining the market is always the best policy for the remaining organizations which are currently not in the market.

However, China and Russia prefer trading with other countries within their own organizations.
