Saudi Arabia:
Netanyahu was apparently referring to ties with Saudi Arabia.

the Kan public broadcaster reported Saturday:
Israel is pushing for the establishment of a negotiating team to hold talks on official relations with the Gulf state, adding:
that the Trump administration wants to achieve peace between Jerusalem and Riyadh as part of the US president’s vision for a
“Golden age of peace in the Middle East.”

Saudi Arabia did not join the 2020 accords and has never recognized Israel.

Normalization with Saudi Arabia has been all but shelved due to the war in Gaza as well as Riyadh’s demands that Israel establish a diplomatic horizon for a future Palestinian state.

However, Trump said ahead of his return to the White House last month that he hoped to use the momentum of the Gaza ceasefire deal to expand the Abraham Accords to include Saudi Arabia.

Qatar:
US special envoy for the Middle East Steve Witkoff has said that Qatar, which along with the US and Egypt, mediated the Gaza ceasefire, is also a candidate for normalization.

Abraham Accords:
The move would expand on the Abraham Accords, through which Israel established relations with the United Arab Emirates, Bahrain, and Morocco during Trump’s first term in office.
