Secretary of State for Northern Ireland Theresa Villiers is meeting business leaders in Belfast to find out how the city is coping after another weekend of trouble over the union flag.
Ms Villiers is meeting Bob Conbrey, the owner of Home restaurant near Belfast City Hall, who says his business has been affected by the flag protests turning violent.
PSNI Chief Constable Matt Baggott has said the Belfast rioting is being manipulated by criminal gangs.
Young people are being led by the nose to prison, he said, while issuing a plea to parents to control their children.
Mr Baggott added that the police tactics were under constant review throughout the trouble.
PSNI Chief Constable Matt Baggott has said today is one of "overwhelming sadness" following another weekend of violence in Belfast.
He described the latest trouble as "a big challenge" and said the way forward was consistent condemnation of violence and to reassert the legitimacy of politics.
Mr Baggott said Friday's rioting was intense and made more difficult by the sheer scale of the trouble - there were 4,000 out in total and not stewarded.
But he said the trouble was contained, using measured and responsible policing. A more rigid approach would be impossible he added, with safety the top priority.
Belfast traders will attend a crisis meeting on Wednesday to discuss losses caused by the Union flag protests.
The Confederation of British Industry estimated that £15 million was lost over Christmas because some people avoided the area altogether.

It will be held on Wednesday at what was once the most bombed hotel in Europe, the Europa, in Belfast city centre.

Senior politicians from Belfast, Dublin and London will meet this week to discuss the Union flag protests in Belfast, after more than 40 days of road blocks and sporadic violence by loyalists have failed to produce a solution.
Stormont First Minister Peter Robinson and his deputy Martin McGuinness will join Northern Ireland Secretary Theresa Villiers and Ireland's Deputy Leader Eamon Gilmore.
Mr Gilmore said the violence "has nothing to do with real issues around flags and identity in a shared society", and claimed those behind it "are known criminals, intent on creating chaos"
