Chancellor Angela Merkel vowed Wednesday to make China's new "special envoys" feel welcome in Berlin, as she unveiled two eagerly awaited giant pandas at the German capital's zoo alongside Chinese President Xi Jinping. "I think that this event today is a symbol of the relationship between our two countries," said Merkel at the ceremony to introduce Meng Meng and Jiao Qing to the public. "Many friends of the zoo have been gripped by panda fever" since it was confirmed that China would send the rare black and white bears to Berlin, she noted.
