The Scandinavian country said while there was no evidence Norwegian-made ammunition had been used in the devastating conflict, which is nearing three years, there was a high risk related to the UAE's military involvement there.
The UAE is part of a Saudi-led coalition fighting Houthi rebels that control the capital, Sanaa, and much of the country's north.
The coalition launched a massive aerial campaign against the rebels in March 2015, aimed at restoring the government of President Abd-Rabbu Mansour Hadi.
Since then, the UN says more than 60,000 people have been killed or wounded, and another three million displaced.
"The Ministry of Foreign Affairs has decided, as a precautionary measure, to suspend licences that have already been issued for the export of Category A defence-related products to the UAE," the ministry said in a statement.
"This means that no arms or ammunition can be exported to the UAE.
"The armed conflict in Yemen has escalated since autumn 2017, and there are major concerns about the humanitarian situation."
In 2016, Norwegian exports of weapons and ammunition to the UAE rose to 79 million Norwegian crowns ($9.7m) from 41 million in 2015, Statistics Norway data showed.
The country's total arms exports were 1.9 billion Norwegian crowns (roughly $235m), placing it 17th on the list of the world's biggest arms dealers.
