The demonstrations kickstarted reforms that included the government's agreement to the drafting of a new constitution to replace the one inherited from the military dictatorship of Augusto Pinochet and perceived as market-friendly.
Last December, Chile elected a leftist president in Gabriel Boric, who supported the constitution-writing process.
But last month, nearly two-thirds of voters rejected the proposed draft despite the new revolutionary mood, amid concerns that parts of the document were too far-reaching.
Boric, a former student leader who had supported the 2019 protests, on Tuesday called for a new social dialogue to give shape to much-needed social reform.
