“Congratulations to Prime Minister Mustafa al-Kadhimi, his cabinet, the parliament and most importantly the people of Iraq for success in forming a new Government,” Zarif wrote on his twitter page on Thursday.
“Iran always stands with the Iraqi people and their choice of administration,” he added.
Iraq and Iran enjoy good neighborly relations having near 1,600 km of joint border areas.
The Iraqi Parliament on Wednesday gave the vote of confidence to al-Kadhmi and 15 members of his cabinet ministers from 19 proposed personalities for the ministerial posts.
Some 233 out of 329 lawmakers were present in the meeting of the Iraqi parliament. Four candidates for the ministerial post failed to get vote of confidence.
After the vote of confidence, al-Kadhmi officially became prime minister of Iraq.
