The UK will pay France £8m more a year under a revised deal to try to stop people crossing the English Channel in small boats.
The money will pay for increased surveillance of French beaches, whilst UK police officers will also be able to observe patrols within France.
French officers patrolling the coast to try to stop people setting off will rise from 200 to 300 over five months.
PM Rishi Sunak said he was "confident" the crossings could be brought down.
However, he warned there was no "single thing" that could "fix" the situation, promising "even greater cooperation" with France in the months ahead.
BBC News home affairs correspondent Daniel Sandford said that while the expanded deal would further disrupt the people smugglers operating in France, it was unlikely to end their trade.

The deal had been close for several months but the French government were reluctant to finalise it until there was a stable government in the UK, our correspondent added.
Foreign Secretary James Cleverly said the UK wanted to "significantly" reduce the number of crossings - but declined to set a target for reductions.
