Samsung Electronics on Thursday named a new head of mobile marketing and a new China chief as part of an executive reshuffle.

Samsung said Executive Vice President Choi Kyung-sik had been promoted to lead the mobile division's strategic marketing office as part of a shake-up at the product businesses such as smartphones and televisions. Choi's predecessor, Lee Sang-chul, had been reassigned to oversee Southeast Asian operations.

Kwon Kye-hyun was named head of the China business, where Samsung's smartphone sales have struggled to regain momentum amid competition from the likes of Huawei Technologies, OPPO and Vivo.

Samsung is expected to deliver record profits this year, on the back of a memory market boom and strong sales of its Galaxy S8 smartphones.
