During Vice President Joe Biden's recent visit to China, he complained to the highest officials about the treatment of western reporters. After weeks of anxiety for some two-dozen western reporters, the Chinese government is renewing some press passes. Yesterday, Bloomberg News said its reporters' finally had been granted the annual renewal of their press cards. The New York Times says the same for some, but not all, of its staff in China. Visas will probably follow. But one veteran of 18 years may never return to the country, and others have now been warned.
