BEIJING — Chinese and American officials are polishing off scripts for a ritual that is set to unfold in Washington on Monday and Tuesday. During a meeting known as the Strategic and Economic Dialogue, they will smile across conference tables and talk about cooperating on a range of issues: trade, currency, North Korea.

But that kind of theater seems more removed from events within China than at any time in recent years. In the past three months, some significant foreign groups have been subjected to intensifying pressure from the authorities, reflecting growing fears here about the influence of foreigners and Western liberal ideas.

Good will between the United States and China is scarce. At the meetings this week, the Americans are expected to talk bluntly about human rights, while the Chinese government has already increased its criticism of the West, with some officials telling foreign diplomats that they believe the United States is fomenting revolution.

At least 60 activities organized by the United States Embassy in Beijing — including cultural forums, school programs, ambassadorial visits — were canceled between February and April because of interference by the Chinese authorities, and some European missions have been similarly pressured. Several university conferences involving foreigners have been canceled, and the Ministry of Education is stepping up warnings to Chinese scholars heading abroad that they not take part in “anti-China” activities or engage with groups that promote democracy.
