"We know from our own history the meaning of surviving tragedies, and we are confident that the Chileans will overcome this sad moment," Erekat said in a statement.
The message came after Chile was hit on Saturday by an 8.8 magnitude earthquake that killed at least 300 people and destroyed the homes of two million others.
Erekat noted that Chile has the largest Palestinian community outside the Arab world, with 300,000 people living between Santiago and Concepcion, a city to the south near the quake's epicentre.
