Companies from Iran, Israel, China, Russia, and the United States will showcase military equipment at an arms expo in Hanoi in December, Vietnam's defense ministry said. The expo will bring together defense companies from Israel and Iran, who have launched missile attacks and airstrikes on each other in the past year. Vietnam has been seeking to diversify its military supplies and reduce reliance on Russia. The country also intends to use the fair to strengthen cooperation with foreign partners to boost its growing domestic industry.
