Possible September Surprise For China's Second Manned Launch
....
The timing of the mission could also have a political angle.
Internationally, China is active on many fronts at the present, ranging from
controversies over export quotas for clothing to Europe, to the possible
return in the near future of the six party talks on North Korea in Beijing.
Senior officials in the Communist Party could feel that launching Chinese
astronauts as soon as possible could improve China's image in one, or
several of China's current international initiatives.

A China space launch isn't going to cause Europe
to change its clothing quotas, nor will it have
any effect on Korea's leader. This is just
nonsense.

Another attraction for launching in September an early mission is the
upcoming meeting between Chinese President Hu Jintao and US President George
W. Bush. NASA's recent problems could also make the success of China's
fledgling human spaceflight program seem more significant.

More nonsense. Pres. Bush is more interested in
China's growing submarine fleet and in its recent
twin spysat launches than he would ever be in a
repeat Shenzhou mission.
