Diamond Plaza is a Grade A office-retail-residential complex located at 34 Le Duan, Ben Nghe Ward, District 1, Ho Chi Minh City – developed and operated by IBC (International Business Centre Co., Ltd.), completed and opened in 1999. The building is officially positioned as “A Result of Korean-Vietnamese Diplomacy” – one of the landmark cooperation projects between the two countries during the early years of economic integration.
IBC is a joint venture between VNSTEEL (Vietnam Steel Corporation) and POSCO Engineering & Construction (South Korea), the firm that directly constructed the complex. In 2016, Lotte Group acquired POSCO’s stake through Lotte Shopping Holdings and joined the IBC joint venture, bringing the Lotte retail brand into the complex.
34 Le Duan is one of the most historically significant and prime locations in Ho Chi Minh City. The building has three street frontages – Le Duan, Pham Ngoc Thach, and Nguyen Van Chiem – and sits directly behind Notre-Dame Cathedral and the Central Post Office, facing April 30 Park and approximately 300 m from the Reunification Palace. This positioning creates a uniquely cultural, diplomatic, and historical intersection that no other building in the area can replicate, given its proximity to numerous foreign diplomatic missions and consulates.
