Britain's foreign secretary says his government will ensure the rights of Romanians living in Britain are protected after Brexit — though he didn't give details.

Boris Johnson said the 500,000 Romanians currently in Britain are "hugely valued members of our society," and that "we would be crazy to let them go back to Romania" in an interview published Tuesday by Romanian national news agency Agerpres.

The rights of Europeans living in Britain are one of the key issues in the talks over Britain's exit from the European Union.

Johnson, who's on a two-day visit to the Czech Republic, Romania and Slovakia, said Britain wants to continue attracting talented, ambitious and innovative people after Brexit.

British Prime Minister Theresa May is preparing to meet with the president of the European Council as she tries to break the deadlock in negotiations on leaving the European Union.

May holds talks Tuesday with Donald Tusk amid the fourth round of Brexit negotiations in Brussels. The meeting comes just days after May proposed a two-year transition period to smooth Britain's departure from the bloc.

EU negotiator Michel Barnier says he is "eager" to understand how May's speech will be turned into a negotiating strategy. The EU wants guarantees on financial commitments, citizens' rights and the Irish border before discussing future trade relationships.

Brexit Secretary David Davis says the UK is "committed" to reaching a solution and "there are no excuses for standing in the way of progress."
