Representatives of Libya's interim government will join US Secretary of State Antony Blinken as well as the foreign ministers of France and Egypt at the UN-sponsored talks.
The trip aims to put into practice President Joe Biden's desire to tackle issues driving migrant arrivals to the southern border of the United States, said Julie Chung, the acting assistant secretary of state for the Western Hemisphere.
During almost two hours of discussions in Reykjavik, Blinken also expressed US concerns on the health of jailed Kremlin critic Alexei Navalny and the "repression" of opposition organisations.
The Israeli Air Force destroyed a building housing The Associated Press and Al Jazeera offices and claimed that Hamas used the building for a military intelligence office.
However, the US Secretary of State Antony Blinken said he has not seen any information provided.
Like Russia, China also stands accused by Western intelligence of unleashing trolls on social media, and of using foreign-language arms of its state media to channel an aggressive line on issues such as the plight of Uyghurs in Xinjiang.
Blinken said China is "the one country in the world that has the military, economic, diplomatic capacity to undermine or challenge the rules-based order that we care so much about and are determined to defend.
