"It is important to achieve on schedule the quantified reform targets of international financial institutions set by the G20 Pittsburgh Summit and increase the representation and voice of emerging markets and developing countries," Hu said.
On trade liberalization and facilitation, Hu urged all parties to properly handle trade disputes and reject protectionism.
"The main parties to the Doha Round negotiations should demonstrate sincerity and flexibility to reach comprehensive and balanced outcomes at an early date and facilitate the establishment of an open and mutually-beneficial multilateral trade regime," he said.
On the improvement of the international financial supervisory and regulatory regime, Hu said it should expand its scope, specify responsibilities, adopt universally accepted standards and norms and strengthen mechanisms.
"There should be supervision over the macroeconomic policies of major reserve currency issuing economies and over sovereign credit rating agencies."
Hu urged all parties to "embrace a stronger sense of responsibility and morality and work for balanced global development."
"It is important to scale up input in development and ensure development resources and at the same time respect each other's development model chosen in the light of national conditions and policy space," he said.
On the High-Level Meeting on the Millennium Development Goals (MDGs) scheduled for the coming September by the United Nations, Hu said the international community, particular developed countries, should honor their commitments in increased assistance, debt relief, market access and technology transfer and help developing countries promote economic growth, improve people's well-being and meet the MDGs.
Hu left Brasilia on Thursday for home after attending the BRIC summit and paying a state visit to Brazil. He headed home earlier than originally scheduled because of a strong earthquake in northwestern China that has killed at least 760 people. He also postponed visits to Venezuela and Chile.
Before travelling to Brazil, the Chinese president attended the Nuclear Security Summit in Washington on April 12-13.
