Datuk Seri Najib Tun Razak said today Malaysia's cordial relations with Saudi Arabia have opened up many opportunities for cooperation in core sectors such as the economy and education.

The Prime Minister said he was confident the cooperation would bring about great benefit for the two countries and their peoples.

"The Saudi Arabian government has provided much assistance to Malaysians in many areas, including visa facility, emergency relocation of students and such," he said in a post on his blog, www.najibrazak.com.

He urged all quarters to practise the concept of Wasatiyyah or moderation which he said was a concept based on the history of Prophet Muhammad in integrating the Muhajirin and Ansar groups of people.

Najib said Muslims should unite and support efforts to unite them, and not quarrel among themselves.

The Prime Minister had made a three-day visit to Saudi Arabia beginning Friday.

Commenting on the visit, he said he was able to meet and chat with Malaysian students and professionals there.

"Many Malaysians are there and I prayed for all of them to excel in their education and jobs," he said.

Najib said he also performed the 'umrah' and visited the Knowledge Economic City, Dar Al Madinah Urban and the Built Heritage Museum.
