It's been claimed in connection with the US bombing of the Chinese embassy in Belgrade that:
In February 2011 The Sunday Times published an article stating that an unpublished memoir by former Chinese President Jiang Zemin recounts how Serbian forces were allowed to use the Chinese embassy, and that privately the U.S. showed evidence of this activity to the Chinese.
However, it seems there's virtually no other evidence/context that Jiang has written an "unpublished memoir". Since he was a (formal) head of state of a big country, I'd expect at least some other interesting bits to have come out his memoir(s). Yet nothing else appears to have surfaced in the English press. The Wikipedia bio of Jiang (unlike the article on the bombing), makes no mention whatsoever that Jiang might have written an "unpublished memoir". So, did he actually do that? What evidence is there besides a few claims in relation to the bombing that Jiang has written an unpublished memoir?
