An all-party meeting convened by the Tamil Nadu government on Monday resolved to allow Vedanta``s Sterlite Industries in Tuticorin to produce oxygen for a four-month period amid surging covid cases, paving the way for the partial reopening of the copper smelter closed in 2018 over pollution concerns.

The unit was sealed by the state government in May 2018, days after 13 agitators were killed in police firing during a violent anti-Sterlite protest in the southern district.
