However, UN officials have expressed disappointment that more money was not given for emergency relief for earthquake survivors over the next six months.
Officials said just $111 million has been given specifically for urgent relief, with most of the other pledges at the 26 October donor conference in Geneva earmarked for long-term reconstruction projects.
UN officials warned that tens of thousands of survivors remain at risk of death due to living outside in remote areas as winter approaches.
The new pledges include $250 million from the Islamic Development Bank, $50 million from the United States, and 50 million euros from the European Union.
The 7.6-magnitude October 8 quake has, according to official statistics, killed more than 54,000 people and left up to 3 million homeless.
