This is because the phrase "with a view to" is commonly followed by a gerund (a verb ending in "-ing").

While "to" might initially seem to be part of the infinitive verb (like "to find"), in this specific phrase, "to" functions as a preposition. Prepositions are followed by nouns, pronouns or gerunds (verbs ending in -ing). Therefore, the correct construction is "to finding," where "finding" serves as a gerund.

If the phrase were structured differently, such as "He went abroad to find a business partner," it would be correct to use "to find" because here "to" is part of the infinitive verb.
