Hu made the comments ahead of his visit to Kazakhstan, Russia and Ukraine June 12-20, Xinhua, China's state news agency, reported Saturday.
Hu said progress is being made against terrorism through the joint efforts of the international community, but more needs to be done.
"But at the same time, we should see that the international anti-terrorism situation is still severe, and some terrorist organizations are still active," Hu said. "The international community should follow the guidance of the Charter of the United Nations and other recognized international laws and rules, strengthen cooperation and fight against terrorism together."
Hu said political instability in parts of Asia and North Africa, coupled with the global financial slowdown, has made fighting terrorism more difficult.
"We should work together to seek common development and make unremitting efforts to build a harmonious world of lasting peace and common prosperity," Hu said.
