A UK-EU summit is likely to pave the way for a deal which could substantially reduce the impact of the Irish Sea border.
The UK wants to reset its post-Brexit relationship with the European Union ( EU) after years of tension.
Monday's summit is expected to include an "agreement to agree" on trade issues, including the trade in food and agricultural products.
If a full agri-food deal follows, potentially later this year, that will reduce the need for checks and controls on products being sent from GB to Northern Ireland.
It could mean the end of 'Not for EU' labelling and the removal of most physical checks on goods.
One food business in Belfast said the reset cannot come soon enough and that immediate measures are needed to help small firms.
BBC News NI first spoke to the owners of Arcadia Deli in 2020 before the sea border started to be implemented. They have faced continuous struggles with the processes needed to get products from GB.
Co-owner Laura Graham-Brown said that new sea border rules on parcels have made the situation much worse in the last month.
"Our partners in England have decided they are not supplying Northern Ireland until further notice until they can get some clarification on how to make it easier," she said.
"That is our biggest distributor so it is starting to tell on our counter as it becomes increasingly empty."
