The International Monetary Fund has backed Saudi Arabia's sweeping economic reform plan.
The IMF said the kingdom was cutting spending at the right speed to cope with a huge state budget deficit caused by low oil prices.
Late last month, Deputy Crown Prince Mohammed bin Salman announced steps to reduce the kingdom's dependence on oil exports over the next 15 years.
These steps included subsidy cuts, tax rises, sales of state assets, a government efficiency drive and efforts to spur private sector investment.
The IMF had for years been urging Saudi Arabia to adopt many of those measures, and said the reform plan aimed for "an appropriately bold and far-reaching transformation of the Saudi Arabian economy". 
"The supporting policies that will be announced in the coming months are expected to set out how these goals will be achieved," IMF official Tim Callen said after leading a team to Saudi Arabia this month for annual consultations with the Fund.
"To ensure their success, the reforms will need to be properly prioritised and sequenced, and the appropriate pace of implementation carefully assessed."
Riyadh has been cutting spending and trying to raise fresh revenues as it grapples with its budget deficit, which totalled $98 billion in 2015.
The IMF predicted the deficit would stay very large this year, at about 14% of gross domestic product compared to 16% last year.
But it welcomed the government's spending controls and changes to domestic energy prices announced last December, saying that "fiscal policy is appropriately adjusting to the drop in oil prices."
The Saudi economy is expected to grow 1.2% this year, slowing from 3.5% in 2015, the Fund said.
The IMF also said it approved of the way in which the government was financing its deficit with a combination of drawing down its financial reserves and issuing debt at home and abroad.
The Fund has been encouraging some North African states to make their foreign exchange rates more flexible to cope with big current account deficits.
But it took the opposite tack towards the external deficit which Saudi Arabia is running because of cheap oil, saying the riyal's peg to the US dollar was continuing to serve the economy well.
Market interest rates in Saudi Arabia have been rising sharply as the government borrows from banks to finance its deficit.
But the IMF said the Saudi banking sector was strong and well-positioned to weather a slowing economy, and that tightening liquidity was not yet hurting credit growth.
Two cornerstones of the Saudi reform plan are the sale of a stake of up to 5% in national oil giant Saudi Aramco, which could fetch tens of billions of dollars, and a build-up of the government's Public Investment Fund into a global investment vehicle.
The IMF urged Riyadh to make both institutions more transparent and to integrate them into a new fiscal policy apparatus which the government is creating to make spending decisions more efficient.
