DUBAI, United Arab Emirates — Qatar’s emir proposed on Tuesday that the Arab League create a $1 billion fund to protect the Arabic and Islamic heritage of Jerusalem, the disputed holy city that remains one of the most intractable issues in the Israeli-Palestinian conflict.

The emir, Sheik Hamad bin Khalifa al-Thani, said he would contribute $250 million to the fund.

He also proposed a special meeting “at the nearest time possible” to promote Palestinian reconciliation between the Fatah and Hamas political factions and the formation of a new Palestinian transitional government.

His proposals, made at a two-day Arab League summit meeting in Doha, Qatar, primarily devoted to the Syria conflict, reflected the emir’s increased political influence in Middle East politics and the vast sums of oil-wealth he has used to exert it. Qatar, an important United States ally, played a decisive role in the revolution in Libya and in financing the insurgency in Syria.
