The world's top particle physics lab has admitted Pakistan as an associate member.

Rolf Heuer, director general of the European Organization for Nuclear Research, known as CERN, says he signed a document Friday in Islamabad in the presence of Prime Minister Nawaz Sharif that admits Pakistan if the government ratifies the associate membership.

Heuer said in a statement Friday that Pakistan has been "a strong participant" in CERN research since the 1990s and bringing nations together in a peaceful quest for knowledge and education is an important part of the lab's mission.

The status upgrade means nuclear-armed Pakistan will have more access and say in the research, and that it will be able to bid for contracts, but also that it must contribute more financially each year to the facility.
