Ahead of an official visit to Britain next week, French President Nicolas Sarkozy would like to underline his commitment to NATO, The Times quoted senior ministers in Britain's Ministry of Defence (MoD) as saying.
The MoD said France would send more than 1,000 soldiers to either the south or east of the country.
French diplomats stressed that no decision had been taken yet.
The Times reported that Sarkozy intended to tell Prime Minister Gordon Brown about the plan during his state visit to Britain on Thursday.
An official announcement would be made at the upcoming NATO summit in Bucharest at the beginning of April.
France currently has some 1,900 soldiers in Afghanistan.
Meanwhile, a report in The Guardian daily said that Sarkozy also planned to discuss Franco-British cooperation on a new generation of nuclear power plants.
By developing new nuclear technology together, the two countries could contribute to reducing climate change, the report said.
France produces some 80 per cent of its electricity from nuclear power, while Britain only produces 20 per cent, the report said.
Sarkozy and his wife Carla will be guests of Queen Elizabeth II on Wednesday and Thursday.
