Vietnam is the confirmed host of APEC 2027. The clearest official confirmation is the 2024 APEC Leaders’ Machu Picchu Declaration, which says the upcoming host years are
Korea (2025), China (2026), and Viet Nam (2027). 
Vietnam has also moved from proposal to preparation.
Vietnam’s government says it set up the National Committee for APEC 2027 in July 2025, and the committee is led by Deputy Prime Minister and Foreign Minister Bui Thanh Son. 
As for location, Vietnam’s government and official state-linked reporting say the main venue for the APEC 2027 Economic Leaders’ Week is planned for Phu Quoc, with preparation tied to projects such as the APEC Conference Center, APEC boulevard, and Phu Quoc International Airport expansion. 
So the practical takeaway is:
Host economy: Vietnam 
Status: officially confirmed and already in active preparation 
Likely main host city/area: Phu Quoc
