Secretary of State Hillary Rodham Clinton is calling on China to embrace political reforms and assume the responsibilities of being a world power in the 21st century.
In a speech Friday ahead of a state visit next week by Chinese President Hu Jintao, Clinton said that US-China relations are at a "critical juncture."
She urged both nations to build a "positive, cooperative, and comprehensive relationship."
Clinton says they should cooperate on shared economic and security challenges. She urged China to use its "unique ties" with North Korea to persuade it to end its nuclear program.
Clinton called for the release of jailed Chinese dissidents. She said respecting human rights would benefit China's "long-term peace, stability, and prosperity."
