GM Korea CEO James Kim will depart 31 August to become the full-time president of the American Chamber of Commerce in Seoul, according to a local media report.

The Korean-American CEO is resigning due to personal reasons, the company told the Korea Herald. His successor will be named later.

"We thank Jim for his contributions to GM Korea over the past two years," Stefan Jacoby, GM executive vice president and president of GM International, was quoted as saying.

"He has been a tireless promoter of our company. Jim has driven domestic sales, helped build the equity of our brands, and reached out to our customers in new and innovative ways."

Kim joined GM Korea in June 2015 as chief operating officer from Microsoft Korea, where he had served as country manager and CEO since February 2009. His previous roles include CEO of Yahoo Korea and Asia regional vice president of Overture (a wholly owned subsidiary of Yahoo).

He was promoted to CEO in January 2016. He will serve as an adviser to GM Korea, from 1 September, the report added.
