No. San D'Oria (Technically Elvaan since Sandy didn't exist then) had issues with Windy. The Elvaans just conveniently found an ally. Given they had no reason to interfere and were essentially freeing Elvaans (See Age of Magic into Age of Power), their action was benevolent. In fact, they intended to maintain relations for several decades after, but a coup occurred and Vo Dho destroyed Du Dha's epitaphs to begin imperialism. So Sandy (Elvaans) was the main benefactor and relations were torn through domestic upheaval instead of blatant "fuck thou" methods.
