Transport and Intelligence Minister Yisrael Katz, who arrived in Muscat on Sunday, is expected to make his pitch at the International Road Transport Union, AFP news agency reported.
The Tracks for Regional Peace initiative calls for a rail link connecting Saudi Arabia with the Mediterranean Sea, according to local media.
The line would extend from Haifa, Israel’s largest port, passing through Jordan before connecting with existing railways in the Gulf.
The trip comes on the heels of a surprise visit by Israeli Prime Minister Benjamin Netanyahu to Muscat late last month where he met Oman’s Sultan Qaboos bin Said – the first such visit in more than 20 years by an Israeli prime minister.
The trip was a coup for Netanyahu, who wants to bolster ties with the Arab world in the face of the perceived expansion of Iranian influence across the region.
Last month, Katz said he had presented the plan to German Chancellor Angela Merkel, whose government had expressed interest in participating in the project.
Separately, Israeli Sports and Culture Minister Miri Regev attended a Judo tournament in the United Arab Emirates, where one of the country’s athletes won gold.
Regev’s emotional appearance at the Judo Grand Competition’s award ceremony in Abu Dhabi was unprecedented and sparked a backlash on Arab social media, given her political leanings. She is an outspoken nationalist popular with Israeli hardliners.
In Abu Dhabi, Regev also toured the grand Sheikh Zayed Mosque. Wearing a loosely wrapped headscarf and the traditional floor-length gown known as an abaya, she was warmly welcomed by local officials.
While Israel has full diplomatic relations with only two Arab states, namely Egypt and Jordan, analysts say the country is trying to ride on a wave of anti-Iran sentiment in the region to boost its popularity and normalise ties with its historic enemies.
Netanyahu and members of US President Donald Trump‘s administration argue that a normalisation of Arab-Israeli ties is conducive to peace with the Palestinians.
The Trump administration is pushing to bridge relations between Israel and Saudi Arabia as it seeks an Israeli-Palestinian peace settlement.
Trump’s Middle East envoy Jason Greenblatt welcomed Katz’s visit to Oman, tweeting: “These efforts support our efforts.”
Israel’s occupation of Palestinian territory, however, remains a major obstacle to official recognition by other Arab countries.
