China is intentionally mischaracterising World War Two-era documents to put pressure on, and isolate, Taiwan, as those accords made no determination of the island's ultimate political status, the de facto U.S. embassy in Taipei said. The 80th anniversary of the war's end has been marked by a bitter dispute between Taipei and Beijing on its broader historical meaning and relevance today. Beijing says documents such as the Cairo Declaration and Potsdam Proclamation support its legal claims of sovereignty over the island, as they call for Taiwan to be "restored" to Chinese rule at a time when it was a colony of Japan.
