Addressing the 75th session of the United Nations General Assembly on Friday, Abbas said the so-called plan would effectively annex 33 percent of Palestinian land, a clear violation of previous international accords.
“The Palestinian nation will continue with its endurance and resistance, will never surrender and will eventually be victorious,” Abbas said.
The Palestinian president called on UN Secretary-General Antonio Guterres to launch an international conference that can make way for “a genuine peace process” early next year.
“Until when should the cause of the Palestinian people remain without a fair resolution? A solution should be conceived on the basis of international regulations.”
“Security, peace, stability and coexistence are not possible under occupation,” he added, Press TV reported.
Abbas added that Israel and the US seek to subvert international regulations and accords with the “deal of the century.”
“The Palestinian Liberation Organization has not granted any individual or country permission to represent it or the people of Palestine,” he noted.
The PLO, which Abbas also chairs, has been historically regarded as the official representative of the Palestinian people in international agreements related to Palestine.
The Palestinian president also censured Bahrain and the United Arab Emirates for the formalization of ties with Israel earlier this month.
The states become only the third and fourth Arab states to establish formal ties with the occupying regime after Egypt and Jordan.
Abu Dhabi and Manama's agreements with Israel received condemnation from Palestinians as a betrayal of their cause, a sentiment echoed by Iran and Turkey and Muslim authorities throughout the region.
Amid increasing Israeli aggression, the Gaza-based Palestinian resistance movement Hamas and the Fatah Party - which rules the West Bank as a faction of the PLO - have pledged unity against Israel’s annexation plans.
On Thursday, the two groups reached a deal to hold the first general elections across Gaza and the West Bank in nearly 15 years.
According to reports, parliamentary and presidential polls will consequentially be scheduled within six months.
