The Gulf of Tonkin is a gulf bordered by China and Vietnam. This map shows the Gulf of Tonkin highlighted in blue on shaded relief, with the surrounding coasts, rivers, borders and major cities.
How to read this map
Countries with a coast on the Gulf of Tonkin: China and Vietnam.
The blue outline marks the Gulf of Tonkin as mapped by Natural Earth. Towns and cities on the map include Hanoi, Nanning, Haikou, Haiphong, Zhanjiang, Maoming, Yulin and Huế. Labeled countries: Vietnam.
Greens show lower elevations; tan and brown show higher land, with pale tones toward the highest terrain. Shadows emphasize the slopes, and vertical relief is exaggerated so landforms are easier to read. Dashed lines show country borders.
The relief uses Terrain Tiles (SRTM, GMTED2010 and ETOPO1 elevation data). Rivers, lakes, borders and the outline of the Gulf of Tonkin come from Natural Earth, and the figures on this page from Wikidata. Natural Earth draws features at a small scale, so the outline is a guide to where the Gulf of Tonkin is, not a surveyed boundary.
