The Mexican government reproached a Korean supervisor at a plant in the central state of Queretaro and offered the victim all the support necessary.

Economy Secretary Bruno Ferrari gave instructions to his department's representative in Queretaro to provide all possible help to Jorge Alberto Zamora, an employee of Sam Won Mexico, which is a supplier to Korean electronics giant Samsung.

In an incident that was caught on video, supervisor Kim Jaeoak shook and hit Zamora, 23, in the face. The worker was fired several days later.

The video was posted on the Internet and aroused indignation in Queretaro and around the country.

Zamora filed an assault charge against Kim.

While acknowledging the need to "favor and promote foreign investment in our country," Ferrari said Mexican authorities will not tolerate "attitudes that infringe on the dignity and safety of workers."

The incident was also criticized by the Queretaro government, the South Korean Embassy in Mexico City and Samsung Electronics Mexico.

Sam Won and Samsung Eletronics Mexico also offered a public apology to the affected worker and his family. EFE
