Mr Haider al-Abadi said the incoming President had told him in a telephone conversation that the US would not only continue but increase its support of the Middle Eastern country’s military efforts to defeat the terrorist organisation.
The news comes as Iraqi fighters continued to push ISIS out of country’s second largest city Mosul.
The city is a key battleground in the fight against ISIS as it is the last urban stronghold of the terrorists and removing the organisation from the city would almost inevitably mean the defeat of the forces in the country.
Al-Abadi told Associated Press: “It is in the interest of the United States and Iraq to keep this relationship.
“I am eager to keep this relationship because it’s good for us and it’s good for everyone else.
“In my telephone call with President-elect Trump, he assured me that US support will not only continue, but it is going to be increased. So, I think am going to be looking forward to more US support at this time.”
The Iraqi Prime Minister said the increased support would take the form of help with training and arming the Iraqi troops.
He added the support was “very helpful for us and is very helpful for the United States”.
He said: “We have seen the whole organisation collapsing in terms of standing in the face of our own armed forces.”
Al-Abadi said that he remained hopeful that with US support Mosul could be freed from ISIS control by the end of the year.
While he declined to give a precise timetable he did state that forces had surrounded the city and continued to make progress in their fight.
He also declined to say how many Iraqi troops have been killed since the operation began six weeks ago but said the rate of battlefield losses was “sustainable.”
Back in September Mr Trump, during the election campaign, had stated that he would “take the oil” from Iraq as a form of “reimbursement” for US help.
But al-Abadi dismissed these statements saying: “I am not going to judge the man by his election statements.
”I am going to judge him by what he does later.
“The Iraqi people will not allow any country to take possession of their own resources.”
There are now some 6,000 US troops in the country, including 100 special operations forces embedded with Iraqi troops for the Mosul operation, according to the Pentagon.
