British Home Secretary Suella Priverman arrived in Rwanda on Saturday for a two-day visit aimed at speeding up a deportation deal for asylum seekers.
Braverman is expected to discuss a deal under which the East African nation would accept migrants arriving in Britain without permission if British courts confirm the proposals are legal.
The British Home Office said in a statement that Rwanda now agrees to accept "all categories of people transiting through safe countries and making illegal and dangerous journeys to the United Kingdom," and the ministry added that "anyone who comes to the United Kingdom illegally and cannot be repatriated will be a candidate for transfer to Rwanda."
The British government wants to send tens of thousands of migrants to Rwanda as part of a 120 million pound ($146 million) deal London reached with Kigali last year.
The partnership was announced in April 2022, but the first deportation flight, which was supposed to take place in mid-June, was banned by order of the European Court of Human Rights.
The High Court in London subsequently ruled the measure legal in December, but opponents are seeking an appeal in April, possibly to the UK High Court later in the year.
According to British government data, more than 45,<> people entered Britain last year by crossing the English Channel in small boats from France, mostly young men from Albania, Afghanistan, Iran and Iraq.
"Many countries around the world are facing unprecedented numbers of illegal immigrants, and I sincerely believe that this world-leading partnership ... humane, compassionate, just and balanced."
"I'm not going to pre-empt the judiciary's decision, but if we succeed, our vision will be to implement the basis of our agreement as soon as possible," Breferman said.
Rwandan Foreign Minister Vincent Perrota said the proposals "provide better opportunities for migrants and Rwandans alike" and would help achieve the British government's goal of dismantling human trafficking networks.
Activists are challenging the legitimacy of the policy in court, and many charities say the proposal is costly and impractical and would criminalize thousands of genuine refugees who have little avenue to seek asylum in Britain without entering the country.
