US and China talks "unparalleled"

This news item gives me pause for thought:

"US and China talks "unparalleled"
July 28, 2009 Secretary of State Hillary Clinton said the US and China have agreed to cooperate on difficult foreign policy problems such as North Korea and Iran's nuclear programmes as well as counter-terror and climate change.
Mrs Clinton described as unparalleled the range of issues discussed between US officials and Chinese envoys during two days of high-level talks this week.
She also conceded that on human rights both sides had candid and respectful exchanges"

There have been some indications in recent months that China is edging away from supporting the incompetent régimes it is allied to in Burma and North Korea in favour of Aung San Suu Kyi in Burma and less ideological political factions in North Korea that could prove to be more responsible in conforming to international norms of governance and international relations. Now it appears that China and the U.S. have just completed their most frank, productive, and collaborative consultations on bilateral and multilateral relations since China and the U.S. established diplomatic relations in 1979. I feel a sense of cautious optimism as to how this will develop in the months and years ahead. That being said my cautious optimism with regard to Chinese Communist Government intentions has been proven misplaced many times before. But nevertheless I remain realistically hopeful. Best to be neither naive nor the intractable cynic.
