This policy would benefit the state and provide trade  If the government decides to promote mother tongue education for large immigrant groups it will be enhancing mutual understanding between its own population and another nation as the immigrants provide a go between. The state will send a positive message towards the large immigrant groups by allowing them to study in their first language. It will acknowledge the importance of such groups in the national society by providing this additional opportunity. The importance of cooperation between immigrant groups and the state is often recognized, for example in combating extremism, this kind of measure encourages such cooperation as it brings with it the good will of the immigrant community.  On the other hand, promoting diversity will promote understanding between countries. A favorable treatment towards the large immigrant groups will be seen positively by the country the immigrants come from. Having migrants creates a link between the two countries. This may produce clear advantages for both parties, in the form of collaboration, diplomacy and trade. The effect of migrants on trade is often ignored but studies have shown that in the case of Spain from 1995-2008 exports are boosted by having immigrant communities; “doubling the number of immigrants from a certain country in a province leads to an increase of the export values from the destination province to the country of the immigrants’ origin by around 10%.” The reason was because new exporting firms are created – immigrants know the conditions in their own country so can access that market, something that would be impossible without a native understanding of the language.
