From AP:
The Beijing declaration calls for a Palestinian state based on borders that were in place before Israel captured the West Bank, the Gaza Strip and east Jerusalem in a 1967 war.What borders?
Just because Palestinians claim that their state shoul dbe on lands that were controlled by Jordan and Egypt between 1948 and 1967 doesn't mean they are legal borders.
They were armistice lines.
The 1949 armistice between Israel and Jordan said explicitly that they were not meant to be national borders: " The Armistice Demarcation Lines defined in articles V and VI of this Agreement are agreed upon by the Parties without prejudice to future territorial settlements or boundary lines or to claims of either Party relating thereto."
The EU is worse - they use the word "borders" deliberately even though they know quite well that they never were borders.
It reminds me of how the UN defended calling Gaza "occupied" by Israel when it wasn't occupied by Israel - saying that they standardized on the terminology so the actual definition is irrelevant.
