A team of Chinese police officers is being sent to the UK to help identify the bodies of the Morecambe Bay cockle pickers who drowned earlier this month.
Two memorial services have been held for the dead
Lancashire police confirmed a team of five officers is due, although it is unclear when they are coming.
Twenty migrant workers drowned on 5 February when they were caught in the dark on the mudflats by a rising tide.
None has been formally identified yet, although police suspect they know who 12 are from their immigration records.
A Lancashire police spokeswoman said it was hoped the Chinese police could help with the formal identification process.
According to Chinese news agency Xinhua, the country's Ministry of Public Security wants to repatriate the Chinese illegal migrants who survived the tragedy.
And it claims only one of the dead had any identity papers.
The death toll in the tragedy rose to 20 on Sunday when the body of a woman was found on a sandbank in the bay.
Hours earlier, a leading member of the Chinese community, Gina San, had warned that as many as 24 people may have died.
Seven people have been arrested on suspicion of manslaughter and have been released on police bail.
Two survivors and a fishing boss, among those arrested, later released statements denying responsibility for the deaths.
Meanwhile, Labour's Geraldine Smith, MP for Morecambe and Lunesdale, has called for an
inquiry into "inaccurate and misleading" information she claims was sent by the Home Office.
In response to a question from the MP about immigration operations in the area, Home Office Minister Beverley Hughes said in a letter: "A successful police and
immigration operation went ahead in August 2003."
She added: "On this occasion 37 cockle-pickers were arrested."
Ms Smith claimed this raid was about a noise disturbance, not cockle-picking.
