Perhaps you should try some spelling variations:
strategic interactions » strategic directions, strategic information
interactions schemes » integration schemes, interactions become
integration series » integration theories, integrating services, integration schemes
price integration » service integration, policy integration, trade integration
effort strategic » reform strategic, export strategies, reforms strategic
export price » export prices, import prices

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( export price integration series. ) OR ( effort strategic interactions schemes. ))~.
• Adding a wildcard symbol may retrieve word variants: (( export price integration series. ) or ( effort strategic interactions schemes. ))*.
