France and the United Kingdom are expected to come to an agreement to crack down on migrants fleeing to the U.K. via the English Channel, which Britain has complained about for years.

Over 20,000 boats crossed the channel in migration attempts in the first six months of the year, according to the U.K. government, which is now requesting and partially funding France’s initiative to halt small boats used by migrants to travel to Britain. French President Emmanuel Macron and British Prime Minister Keir Starmer are meeting at a summit this week to finalize a deal to block small boats from traveling through the English Channel.
