In Cambodia, rubber is an important agricultural industry crop that produces latex and rubber wood. Cambodia exports most of its natural rubber to Vietnam, Malaysia, Singapore, China, and Spain. This study aimed to assess export competitiveness of Cambodian rubber using Revealed Comparative Advantage (RCA) and Trade Specialization Index (TSI) and to explore strategies for enhancing exports. This research analyzed secondary data from Trade Map and the General Directorate of Rubber (GDR) from 2002 to 2022. Findings show that Cambodia has a significant comparative advantage globally in natural rubber, with an RCA of 18. Particularly, Cambodia demonstrates substantial comparative advantages in its rubber exports to Vietnam, Malaysia, and China. Additionally, it has a high TSI, indicating a strong potential for expanding exports to these markets. However, Cambodia’s reliance on Vietnam for its rubber exports is high, highlighting the need for efforts to diversify its export markets.
