SMITHERS, B.C. -- Hereditary chiefs who oppose a natural gas pipeline in northern British Columbia say they will sign an agreement with the federal and provincial governments that affirms their title and rights.

At the centre of the dispute is Wet'suwet'en opposition to the construction of the Coastal GasLink pipeline through their territory, which set off demonstrations and blockades that shut down large parts of the national economy in February.

A joint statement from the governments and Wet'suwet'en chiefs says they remain committed to implementing the rights and title of the First Nation through the memorandum of understanding.

No details of the memorandum, which was reached in February, have been released.

The statement says there's a lot of work ahead in the negotiation process, including how the three governments will work together.

The Wet'suwet'en have invited B.C.'s Indigenous relations minister, Scott Fraser, and Carolyn Bennett, the minister of Crown-Indigenous relations, to sign the agreement on May 14.
