CitigroupÆs investment research arm has announced the appointment of Choong Wai Kee as head of country research in Malaysia. The appointment marks the fourth new country research head appointed by Citi over the past few months. So far, the bank has named new heads in Hong Kong, South Korea and Thailand.

Upon arriving at Citi in Kuala Lumpur, Choong will take over the reins from Teh Chi Chang, who will now focus on the power, tobacco, print media and gaming sectors in Malaysia. Chang held the head of Malaysian research role for two years.

Choong will report to Adrian Faure, the bank's Hong Kong-based managing director and Asia-Pacific head of research. His responsibilities will include providing analysis on Malaysian country strategy and the gaming and conglomerates sector.

ChoongÆs appointment comes as Citigroup bulks up its research division in Asia-Pacific. For example, the firm recently named Anil Daswani, its former conglomerates research head as its new head of Hong Kong research and then backed this move up with the appointments of Andrew Stotz as head of Thailand research and Michael Chung as head of South Korean research.

Choong comes from BNP Paribas where he was head of equity research. In recent months there have been a slew of departures from the French bank. Earlier this month, it was reported that Michael Ong, head of research at BNP Singapore had departed for a fund management company, along with Pearly Yap, Singapore equities analyst, who also left for a fund management firm.
