Wang met with former U.S. Secretary of State Madeleine Albright in Beijing Thursday, Xinhua reported.
"The two nations should further enhance understanding and mutual trust to avoid politicizing economic and trade issues," he said.
Wang said Sino-U.S. relations are "moving forward through difficulties."
Trade cooperation is expanding and the Chinese and U.S. are more closely linked than ever, Wang said.
"China will not change its policy of opening up, and the investment environment will also be improved," he said, asking foreign entrepreneurs to be confident and patient.
Albright agreed that a sound U.S.-China relationship was critical to the world economy.
