The government of Singapore sent a military medical mission to East Pakistan which arrived at Chittagong on December 1, 1971. They were then deployed to Sandwip where they treated nearly 27,000 people and carried out a smallpox vaccination effort. The mission returned to Singapore on December 22, after bringing about $50,000 worth of medical supplies and 15 tons of food for the victims of the storm. The Japanese cabinet approved a total of $1.65 million of relief funds in December. The Japanese government had previously drawn criticism for only donating a small amount to relief work. The first shipment of Chinese supplies to East Pakistan was a planeload of 500,000 doses of cholera vaccine, which was not necessary as the country had adequate stocks. The Chinese government sent $1.2 million in cash to Pakistan. Mohammad Reza Pahlavi declared that the disaster was also an Iranian one and responded by sending two planeloads of supplies within a few days of the cyclone striking. Many smaller, poorer Asian nations sent nominal amounts of aid.
