The three source documents discuss the same event and contain overlaps in content: the fact that Meng Wanzhou was arrested is stated explicitly in Source 1 and 3 and indirectly in Source 2.
some sources contain information not mentioned in the others which should be included in the summary: Source 3 states that (Wanzhou) is being sought for extradition by the US while only Source 2 mentioned the attitude of the Chinese side.
