South African President Thabo Mbeki is in Ivory Coast to try to restore calm after two days of violence.
Anti-French feeling is still running high in the capital
Mr Mbeki said after talks with President Laurent Gbagbo that the Ivorian leader was committed to solving the country's problems peacefully.
Foreigners have been targeted amid confrontations involving thousands of Mr Gbagbo's supporters.
Meanwhile France has denied it wants to overthrow Mr Gbagbo, and that its troops shot dead 15 demonstrators.
On Saturday, French troops destroyed the small Ivorian air force in retaliation for a government air strike that killed nine French soldiers.
The incidents sparked a wave of anti-French violence that continued into Monday. The Red Cross said more than 600 people were hurt.
Joint patrols began on Monday evening in the commercial centre Abidjan with Ivorian and French troops, and peacekeepers from other countries within the UN force.
But the BBC's James Copnall in Abidjan says a greater show of force is only likely to provoke more hostility.

Mr Mbeki met Mr Gbagbo at his residence on Tuesday as large crowds of Gbagbo supporters gathered outside.
He said the Ivorian leader was committed to agreements signed with the northern rebels which brought about a ceasefire 18 months ago, despite this being broken last week by a government offensive and air strikes against rebels.
"I must say I am very pleased by the commitment of the
President, Laurent Gbagbo, to implement in full Marcoussis and
Accra III [peace deals] so that Ivory Coast can go through a
transitional process," he said, quoted by Reuters news agency.
The agency also reported shooting soon after Mr Mbeki left the residence.
He will now report back on the crisis to the African Union, which sent him on the mission.
The demonstrators are currently involved in a stand-off with French troops and foreign residents in the Hotel Ivoire, not far from Mr Gbagbo's residence, where angry militants shouted insults at French President Jacques Chirac.

The BBC's James Copnall in Abidjan describes seeing people dressed in the colours of the Ivorian flag singing and chanting in front of barbed wire erected by peacekeepers around the hotel.
"We are not going to leave," one Gbagbo supporter told the Associated Press news agency. "If I get the French, I can eat them."
At the weekend, tens of thousands of President Gbagbo's supporters marched on the French-held main airport in Abidjan.
They also went on the rampage across the city attacking French targets.
France sent 600 more troops to back up the 4,000 soldiers it already has in Ivory Coast as part of a UN force of 10,000.
