China is to give Zimbabwe a loan of $US950 million to help revive its economy.
Prime Minister Morgan Tsvangirai has been criticised by supporters of President Robert Mugabe for failing to get more support during a recent trip to the West.
Mr Tsvangirai and Mr Mugabe formed a power-sharing government in February.
The United States promised $US73 million in aid while Britain pledged to boost its funding by about $US8 million, taking its total to $US98 million for the year.
Mr Tsvangirai said he had received pledges totalling $US500 million during his trip.
The government says it needs some $US8 billion to rebuild the country following years of collapse.
