Michael Aron, the British ambassador to Yemen, said he will participate in the talks alongside 23 other ambassadors and Griffiths, the United Nations envoy.
Griffiths was in Sanaa earlier this week to meet with Houthi rebel leaders, and he then travelled to Sweden with a Houthi delegation on Tuesday.

Intensified fighting around Yemen's port city of Hodeida has cut port operations by almost half.
"A stable state, important for the region, can not coexist with unlawful militias", Gargash said.
Griffiths hopes to reach a deal on reopening Sanaa airport and securing a prisoner swap and a ceasefire in Hodeidah as a foundation for a wider truce, including a halt to coalition air strikes that have killed thousands of civilians and Houthi missile attacks on Saudi cities.
"Tehran is ready to help worldwide talks to end the crisis and underlines the importance of accelerating providing humanitarian aid to the people", Iran's foreign ministry said in a statement, according to Reuters.
