Japanese Royals Will Probably Skip Beijing Olympics

It is being reported that Japan’s royal family will probably decline an invitation to attend the Beijing Olympics:
The Japanese government thinks it is not a good time for a rare royal visit because of the unrest in Tibet, a recent health scare over Chinese-made “gyoza” dumplings and a spat over disputed gas fields, the Sankei daily said.
“We were planning not to ask royals to go even before the gyoza incident (surfaced in January). It is all the more true now that the Tibetan unrest occurred,” it quoted an unnamed government official as saying.
Japanese authorities have confirmed at least 10 people suffered pesticide poisoning after eating tainted dumplings imported from China.
Chinese Premier Wen Jiabao invited Emperor Akihito and other royals to the opening ceremony of the August Olympics when he visited Japan last year.
The emperor told Wen then that the government decides on the royal family’s foreign trips, a palace spokesman said.
I can see the Tibet situation as a reason not to attend, but why the gyoza incident?
