Business Secretary Kwasi Kwarteng has insisted the UK was working "very effectively" with France to tackle migrant crossings of the Channel, amid a spat with Paris over funding.
The Tory frontbencher sought to play down splits after French interior minister Gerald Darmanin claimed "not one euro has been paid" by Britain of the £54m promised to help deal with the problem.
Home Secretary Priti Patel recently threatened to withhold the funding unless more people were stopped from reaching the UK.
The row came as Sky News filmed dozens of migrants leaving beaches on inflatable boats, and even a canoe, to begin the hazardous voyage unchallenged by French police officers.
Among those rescued by the RNLI after surviving a nine-hour journey was a newborn baby.
It comes as official figures revealed more than 1,100 people crossed the English Channel to the UK aboard small boats over Friday and Saturday.
Numbers released by the Home Office show at least 624 people reached the UK on Friday aboard 23 boats, with 491 people crossing on Saturday aboard 17 boats.
Speaking to Sky News' Trevor Phillips On Sunday programme, Mr Kwarteng said: "All I can say is that we've worked very effectively with the French government so far."
He pointed out joint cooperation had led to nearly 300 arrests, 65 convictions and prevented more than 13,500 crossings.
The cabinet minister added: "It is a good collaborative relationship and we obviously want to improve that.
"Things are actually happening on the ground and I am sure the home secretary is working very hard to make sure that we actually deliver on this very critical problem."
It follows comments made by Mr Darmanin during a weekend visit to Calais to inspect efforts to tackle migrant crossings, when asked by Sky's Europe correspondent Adam Parsons why so many boats were arriving in Britain despite the deal.
Mr Darmanin said: "First off, the British government has not paid, for now, what was promised.
"So, for the moment, there is not a euro that has been paid by the British government following the deal - more or less - that we negotiated with Ms Patel.
"The English are people of honour, so I am certain that it is an accounting delay."
He also insisted the French authorities had taken action to stop the illegal arrivals, including dismantling transit camps and increasing the number of police.
French fisheries workers claim they have been "deceived" by the British government over fishing licence applications and have called on the European Commission to take "retaliatory measures".
And France has again threatened to cut the UK off from energy supplies if the terms of the Brexit deal aren't stuck to.
