Under the agreement, France will significantly expand its coastal security presence, increasing the number of officers tackling irregular migration by more than 50% to reach 1,400 by 2029. The funding from United Kingdom will be partly conditional, with nearly a quarter tied to performance benchmarks assessing the effectiveness of French actions.

The deal follows months of negotiations between United Kingdom and France over renewing the Sandhurst Treaty, which governs British financial contributions toward efforts to prevent migrants from departing French shores.

British authorities have long argued that France needed to do more to stop departures, as crossings by small boats have become a politically sensitive issue in the UK. London had insisted on tighter oversight and conditions on how funds are deployed before agreeing to renew the framework, first signed in 2018 and extended in 2023.

According to the roadmap, funding allocations could be redirected if joint annual assessments determine that the measures fail to deliver sufficient results. French authorities also plan to deploy additional surveillance tools, including drones, helicopters and digital monitoring systems, to reduce departures, particularly those involving so-called “taxi boats.”

Under international maritime law, authorities are limited in their ability to intervene once vessels have left shore, focusing primarily on rescue operations to prevent loss of life.

Official British data shows that 41,472 people reached the UK via irregular small-boat crossings in 2025, the second-highest annual figure since such journeys were first recorded in 2018.

At least 29 migrants died attempting the crossing that year, according to figures compiled from French and British sources.

The two allies agreed that Seoul does not fall under the manipulator designation that the U.S. Treasury Department announces in reports twice a year, Kang Yu-jung told a press conference

Officials at the U.S. embassy in Seoul could not be reached for comment outside business hours.

The administration of President Joe Biden added South Korea to a manipulation monitoring list in November due to its large current account surplus and its sizable trade surplus with the U.S. The government of Donald Trumpkept Seoul on the list in June.

Under a 2015 U.S. law,Washington can take “remedial action” against countries that do not “correct the undervaluation of their currency and trade surplus with the United States”.

The South Korea-U.S. deal is not related to talks on a currency swap as part of bilateral negotiations over Trump’s tariffs on South Korean goods, South Korean officials said.

President Lee told Treasury Secretary Scott Bessent on Wednesday in New York that the Asian country needs a foreign exchange swap in order to make the $350 billion investment it has pledged in the tariff talks, Finance Minister Koo Yun-cheol said on Saturday.

Koo quoted Bessent as saying he would discuss the issue with other U.S. officials and get back to South Korea.

South Korean National Security Adviser Wi Sung-lac reiterated on Saturday that Seoul cannot pay the $350 billion “upfront”, as Trump has suggested in recent days. President Lee told Reuters this month that South Korea’s economy could fall into crisis rivalling its 1997 meltdown if the government accepted the U.S. demands without safeguards.

Koo said he had not heard anything about a Wall Street Journal report that Commerce Secretary Howard Lutnick had discussed raising the $350 billion investment.
