Al-Barazi used his extensive connections with Arab leaders in Saudi Arabia, Jordan, Egypt and Lebanon to garner support for the al-Zaim regime.

[1] Al-Barazi was tasked with conducting secret negotiations with Israel to conclude a peace treaty between the two countries, and to discuss a possible summit between Israeli Prime Minister David Ben-Gurion and al-Zaim.

[1] Al-Barazi was also credited with mediating an agreement between al-Zaim and Lebanese Prime Minister Riad as-Solh which extradited Antun Saadeh, founder of the Syrian Social Nationalist Party (SSNP), to Lebanon where he would be executed.
