Tens of thousands of Chileans marched in Santiago, the capital city, as well as elsewhere in the country on Wednesday.
Students and trade union leaders headed the demonstration, which took place even though President Sebastian Pinera announced a series of social reforms in a bid to quell days of violent protests. Protesters waved banners and national flags and shouted "Chile has woken up."
The first day of the two-day general strike was largely peaceful.
Some protesters erected flaming barricades and clashed with riot police. Police deployed water cannon and fired rubber bullets and tear gas at the protesters.
Two supermarkets were set on fire in the north of Chile, and a hotel was looted near Italia square in Santiago, broadcaster 24 Horas reported.
Chile's largest copper union joins protest
Codelco, the Chilean state mining company, had to shut one mine and drastically reduce operations at a smelter, after workers joined the strike. Six of Codelco's eight divisions were carrying on with the "majority of their operations," the company said in a statement.
The Copper Workers Federation (FTC), which unionizes workers from Codelco, announced late on Tuesday that its workers would join the strike.
Later on Wednesday the FTC trade union called off the strike. They agreed to meet with government officials to improve workers conditions.
On Tuesday the FTC and the National Grouping of Fiscal Employees, among other unions, had continued to back the strike, even after Pinera had announced a social reform package.
The trade unionists who called the two-day strike initially wanted Pinera to discuss the proposed social reforms with grassroots organizations and for him to remove soldiers from the streets.
Reforms announced by Pinera on Tuesday include an increase in the monthly pension, raising the minimum wage and canceling a 92% rise in electricity rates due to take effect next month.
Reform package and strike divide opinions
Chileans responded differently to Pinera's reform package. Some thought that they were not good enough, but others thought that they were a move in the right direction.
Venezuela's socialist president, Nicolas Maduro, on Wednesday celebrated the strikes in Chile, saying that they represented a victory in a battle "to dismantle the neoliberal model."
Pope Francis, an Argentinian, expressed concern over the protest and urged for dialogue.
Concerns over state violence
About 20,000 soldiers are patrolling the streets, nearly 200 people have been injured and some 5,000 have been arrested in the six days of protests.
The UN and human rights groups have expressed concerns about excess force used by police and military after the government ordered a military curfew.
The demonstrations began after students protested the government's decision to increase subway fares in the capital.
The fare hike was canceled, but Chileans continued protesting widespread inequality across the country.
