"I will propose to Parliament, when the opportunity arises, that we send peacekeeping forces to Palestine when we can see how we can push this peacekeeping mission forward," Sánchez told a gathering of Spanish ambassadors in Madrid on Thursday.
Spain must actively participate in rebuilding hope in the area, he said.
The situation there is still unacceptable.
Sánchez also reiterated his support for sending peacekeeping forces to Ukraine.
The Spanish government recognized the state of Palestine in 2024 and is one of Europe's most vocal critics of how Israel has conducted the war in the Gaza Strip.
