From No Right Turn - New Zealand's liberal blog:
Since China's crackdown in Tibet, pressure has come on governments and leaders around the world to show their disapproval by refusing to attend the "oppression Olympics". Now that pressure has borne fruit, with a number of European leaders refusing to attend the opening ceremony:
Donald Tusk, Poland's prime minister, became the first EU head of government to announce a boycott on Thursday and he was promptly joined by President Václav Klaus of the Czech Republic, who had previously promised to travel to Beijing.
"The presence of politicians at the inauguration of the Olympics seems inappropriate," Tusk said. "I do not intend to take part."
Frank-Walter Steinmeier, Germany's foreign minister, confirmed that [German Prime Minister Angela] Merkel was staying away. He added that neither he nor Wolfgang Schäuble, the interior minister responsible for sport, would attend the opening ceremony.
It's a small gesture, but a significant one, which hits the Chinese where it hurts: by denying them the prestige they hope to gain by hosting the games. And with Merkel out, the pressure is now on other major European leaders such as Nicolas Sarkozy and Gordon Brown to follow suit.
An interesting question for Americans is whether their leaders will follow suit. Will Bush and Rice commit to refusing to attend? Will Congressional and Senate Democrats?
As for New Zealand, I doubt Helen Clark will follow. She's already demonstrated that she's willing to walk over Tibetan corpses to get her free trade deal; after that, boycotting the opening ceremony would simply seem hypocritical.
