Police put up barricades there and both vehicles and pedestrians were denied access.
The protesters gathered in two districts of the city - Arts Lois and Porte de Namur - but there were no incidents of violence.
They also put up a barricade near the Franco-Belgian border close to Adinkerque, Belga said.
The "yellow vest" movement in France originally started as a protest about planned fuel hikes but has morphed into a mass protest against President Emmanuel Macron's policies and top-down style of governing.
It has spilled over to some other countries, including Belgium and especially in the country's French-speaking region.
On November 30, a "yellow vest" protest by some 300 people in Brussels degenerated into violence in which two police vehicles were torched.
