Brazilian labor authorities have placed Chinese electric vehicle manufacturer BYD on the country's official list of companies found to have subjected workers to slavery-like conditions, according to government records.

The inclusion on Brazil's so-called "dirty list" relates to labor violations discovered at facilities associated with the Chinese automaker's operations in the country. The list is maintained by Brazilian authorities to publicly identify companies found to have used forced labor or subjected workers to degrading conditions.

BYD, one of China's largest electric vehicle manufacturers and a major competitor to Tesla globally, has been expanding its international presence as part of China's broader push into overseas markets. The company has been investing in manufacturing facilities across multiple countries as it seeks to establish a global footprint for its electric vehicles and battery technology.

Brazil's labor inspection system regularly monitors working conditions across various industries, and companies can be removed from the list after demonstrating compliance with labor standards and implementing corrective measures. The placement on the list can affect a company's ability to access certain government contracts and financing.

The development comes as Chinese companies face increased scrutiny over labor practices in their international operations, with various countries implementing stricter oversight of working conditions at foreign-owned facilities.
