On Tuesday, a British minister asserted the call after a surge in the number of migrant crossings in often unseaworthy small boats.
French officials and the UK’s Immigration Minister Chris Philp met in Paris in wake of growing concerns out of London over the frequency of migrant crossings into Britain from France.
"French authorities are doing a great deal of work... but the sheer numbers crossing the Channel are completely unacceptable. Unacceptable to the French government and unacceptable to the UK government," Philp told reporters.
"So it's quite clear that more needs to be done," he said, adding both sides were now working on a comprehensive action plan.
Britain's right-wing Conservative Party government has looked to increase pressure on France to prevent migrants coming into UK waters.
British Prime Minister Boris Johnson on Monday said illegal migrant crossings were "very bad and stupid and dangerous", adding they needed to be stopped in cooperation with France.
"We are committed to taking action to make this route — facilitated by dangerous criminals — completely unviable and that is an objective the French government shares," said Philp.
