Add as preferred source on GoogleThe UK and Vietnam have agreed on a deal to curb illegal migration, focusing on reducing undocumented arrivals and enhancing bilateral cooperation.
LONDON (Reuters) -Britain said on Wednesday it had agreed to a deal with Vietnam to curb illegal migration in what it described as the strongest Hanoi had ever agreed with another country.
British Prime Minister Keir Starmer, under pressure to reduce the numbers of undocumented migrants reaching Britain to help arrest his government's plunge in opinion polls, struck the deal with Vietnamese Communist Party chief To Lam in London.
Vietnamese nationals were the most numerous among foreign migrants arriving in Britain by small boat from continental Europe in the six months to June 2024, accounting for 17% of all such arrivals in this period, according to official data.
According to the latest government data, small-boat arrivals accounted for 43,000 of the total of 48,000 irregular arrivals in the year ending June 2025.
The deal reached by Starmer and Lam aims to cut red tape and make it faster and easier to return migrants with no right to be in the United Kingdom, the British government said.
"The number of illegal arrivals from Vietnam has already been cut by half, but more can be done," Starmer said in a statement. "Today's agreement shows that through international cooperation - not shouting from the sidelines – we can deliver for the UK and for working people."
Vietnam's paramount leader, Lam has taken a central role in shaping foreign policy since becoming party chief last year, an effort previously led by the president and prime minister.
Starmer's Labour government has seen its popularity slide since it took office last year - partly due to an increasing public backlash over immigration. Under pressure from the surging populist Reform UK party, the government has pledged to slash the number of migrants who arrive illegally.
Polling shows immigration is one of British voters' main concerns after the high cost of living.
A joint declaration following the two leaders' meeting said the partnership would also strengthen political trust, economic cooperation and science and technology. It would also include sectors such as energy and education.
Under another deal struck earlier this year, France agreed to accept the return of undocumented people arriving in Britain by small boats in exchange for Britain agreeing to accept an equal number of legitimate asylum seekers with British family connections.

Illegal migration refers to the movement of people into a country in violation of that country's immigration laws. It can involve crossing borders without proper documentation or overstaying a visa.
Immigration policy refers to the laws and regulations that govern how a country manages the entry, stay, and exit of foreign nationals. It includes rules on visas, asylum, and deportation.
Undocumented migrants are individuals who enter or reside in a country without the necessary legal authorization or documentation, often facing legal and social challenges.
