A group of protesters are taking their campaign to save the HP Sauce factory in Birmingham to the US ambassador.
Wednesday sees two more meetings over the HP Sauce factory
The American company Heinz plans to move production to Holland with the loss of 125 jobs.
Also on Wednesday, Birmingham City Council is meeting Heinz managers to try to persuade them to keep making HP Sauce in Aston.
Birmingham City Council could exercise powers to ensure that the threatened plant remains for industrial use.
The cabinet member for economic regeneration, Councillor Ken Hardeman told the BBC: "That area on which the HP Sauce factory is located and much more of that area is identified in our planning requirements as opportunity land - in other words, light industry or similar to that currently there.
"If Heinz at the end of the discussion feel they have no option but to move, then we would say they may have to be mindful that the planning restrictions on that site will have to be adhered to."
Mr Hardeman added: "There are jobs at stake, a history of that product being manufactured in Birmingham and a history of opportunity - and we want to preserve it."
Wednesday's meeting will also be attended by figures from the Government Office of the West Midlands, Birmingham Chamber of Commerce, Advantage West Midlands and city council officers.
