Vanuatu

The flag of Vanuatu emoji shows two horizontal stripes: red and green, with a black triangle and a yellow Y-shape separating the colors, and a boar's tusk within the triangle. On some systems, it is displayed as a flag, while on others, it may appear as letters VU. If someone sends you a 🇻🇺 emoji, they are referring to the country of Vanuatu.
