Kuwait joined Saudi Arabia the same day in announcing new oil production cuts to be implemented in June, state news agency KUNA reported, citing Oil Minister Khaled al-Fadhel. Kuwait will slash production by 80,000 barrels per day in June, on top of cuts already agreed under a pact by the OPEC+ group of major oil producing countries, al-Fadhel said.

OPEC and its allies in the OPEC+ group agreed last month to cut production by a record 9.7 million barrels per day. Other producers pledged to reduce their output by around 3.7 million barrels per day.

Under the deal, Saudi Arabia's daily production was cut to 8.5 million barrels per day, the lowest level in more than a decade.
