ABU DHABI -- The second round of US-brokered talks between Russia and Ukraine started in Abu Dhabi, a member of the Ukrainian delegation said on Wednesday.

"The next stage of negotiations in Abu Dhabi has begun," Rustem Umerov, secretary of Ukraine's National Security and Defense Council, said in a post on social media platform Telegram.

According to Umerov, also a member of the Ukrainian delegation, the negotiation process started in a "trilateral format" involving Ukraine, the United States and Russia.

"Next, work will be carried out in separate groups ... after which a repeat joint synchronization of positions is planned," he said.

The Ukrainian official stressed that the delegation is working to "achieve a dignified and lasting peace."

Meanwhile, the United Arab Emirates (UAE)'s Ministry of Foreign Affairs stated that the hosting of the talks reflects its balanced relations with all three parties and the international community's confidence in the country's role in facilitating dialogue and creating a conducive environment for constructive negotiations.

The ministry reiterated the UAE's commitment to backing international efforts for a comprehensive and lasting political solution, which would strengthen prospects for peace and stability at both regional and global levels.

The second round of talks is scheduled to run for two days. It follows an initial round held in Abu Dhabi on Jan. 24, which concluded without any concrete agreements or a joint statement.
