In 2002, the Quartet established the Office of the Quartet in East Jerusalem to take "tangible steps on the ground to advance the Palestinian economy and preserve the possibility of a two state solution." Kito de Boer was the head of the Office from January 2015 to June 2017, assuming the position after the resignation of Tony Blair. The objective of the head of the Office is to promote the Quartet’s strategy on Palestinian economic and institutional empowerment, including matters concerning rule of law and economic development, as well as movement and access. The current head of the Office is John N. Clarke.
