JAKARTA, May 27 (Reuters) - Indonesia's anti-trust

agency said on Monday it is investigating the local units of

e-commerce platforms Shopee and Lazada for suspected violations

of anti-competition rules.

The companies are PT Shopee Internasional Indonesia, and PT

Ecart Webportal Indonesia, which oversee the domestic operations

of Shopee and Lazada respectively.

The agency did not elaborate on what the alleged breaches of

anti-competition rules were.

Shopee, owned by Southeast Asian technology firm Sea Ltd ( SE )

, and Lazada, the Southeast Asian arm of Alibaba ( BABA )

, did not immediately respond to requests for comment.

The agency's hearing into the conduct of Shopee would start

on Tuesday, it said, without giving details of a potential

punishment.

The agency found early evidence of violations by Lazada,

which it said is facing a maximum fine of 50% of its net profits

or 10% of its sales earned during the time of the alleged

breaches.

"There are indications Lazada has undertaken discriminative

actions that potentially inhibit competition and indications

that its actions have been harmful to consumers," the agency

said.
