Brazil's state-led oil company Petroleo Brasileiro SA canceled talks planned for Nov. 10 aimed at settling a nine-day strike, FUP, the country's main oilworkers federation, said on Twitter.

FUP members have been on strike at Petrobras, as the company is commonly known, since Nov. 1 in the biggest labor action against the company in 20 years. The union is seeking to force Petrobras to reverse investment cuts and scrap plans to sell assets to pay more than $130 billion of debt, the largest of any oil company in the world.

Petrobras officials were not immediately available to comment on the talks.

Petrobras' press office said on Nov. 10 that the strike was cutting oil output by about 115,000 barrels a day, the same amount as Monday. That is equal to about 5.5 percent of pre-strike oil output in Brazil.
