WASHINGTON (Reuters) - The United States regrets France's decision to recall its ambassador from Washington and will continue to be engaged in the coming days to resolve differences between the two countries, a White House official said on Friday.

       France recalled its ambassadors to the United States and Australia after Australia struck a deal with the United States and Britain which ended a $40 billion deal to purchase French-designed submarines.
