Chinese Premier Wen Jiabao said Sunday that the diplomatic snub and ensuing rebukes against the Chinese delegation during last year's Copenhagen climate summit were "still a mystery."

Wen said he and the Chinese delegation had not received any invitation to a small-scope meeting between several countries' leaders on Dec. 17.

"We haven't received any explanation until now. It's still a mystery to me," Wen said.

Wen made the remarks when being asked to comment on his "decision not to attend a key meeting" before the Copenhagen climate change summit and the Chinese delegation to the Copenhagen conference being perceived as "arrogant."

"It still perplexes me why some people keep trying to make an issue about China (in this regard)," he said.

Wen said he learned from a European country's leader, at a banquet hosted by Danish Queen, about the meeting that would be held later in the evening, and saw China was on the list of the meeting's participating countries.

"I was shocked as I had received no notification that China was invited," he said.
