In his statement, President Saied described the accusations of racism as a campaign against the country "from known sources", without elaborating.
But he added that Tunisia was honored to be an African country and announced a relaxation of visa rules for African citizens, allowing stays of up to six months instead of three without seeking residency, and of a year for students.
Saied said migrants who had overstayed could leave without penalty after many of those authorities sought to deport had proven unable to pay fines for late stays.
During a statement on Feb. 21 telling security forces to expel all illegal immigrants, President Kais Saied called migration a conspiracy to change Tunisia's demographics by making it more African and less Arab.
While Saied denied racism in a statement on Feb. 23, he repeated his view of immigration as a demographic plot. Before Sunday, Saied had not publicly warned of any legal consequences for the attacks.
Police detained hundreds of migrants, landlords summarily evicted hundreds from their homes and hundreds of others were fired from work, rights groups say.
Many migrants said they had been attacked, including being pelted with stones by gangs of youths in their neighborhoods, and rights groups said police had been slow to respond to such assaults.
The Tunisian president painted his crackdown on illegal migration as being a campaign against human trafficking and pointed to a law passed in 2018 against discrimination to say that any verbal or physical attacks on foreigners would be prosecuted.
Opposition parties and rights groups have said Saied's crackdown on immigrants, which coincided with arrests of senior opposition figures, was aimed at distracting from Tunisia's economic crisis.
