U.S. Secretary of State Marco Rubio said Thursday that the U.S. and Russia have exchanged new ideas for Ukraine peace talks after he met with his Russian counterpart in Malaysia Thursday. "There were some ideas exchanged today, some viewpoints that they expressed to us, that I'll take back to the president for his consideration and hopefully it will lead to something," Rubio told reporters after talks with Russian Foreign Minister Sergey Lavrov. Rubio added that President Donald Trump has been “disappointed and frustrated that there’s not been more flexibility on the Russian side" to bring about an end to the conflict. The two men held talks in Kuala Lumpur on the sidelines of the annual Association of Southeast Asian Nations Regional Forum, which brings together 10 ASEAN members and their most important diplomatic partners including Russia, China, Japan, South Korea, European nations and the U.S. The meeting was their second encounter since Rubio took office, although they have spoken by phone several times. Their first meeting took place in February in Riyadh, Saudi Arabia, as the Trump administration sought to test Russia and Ukraine on their willingness to make peace. Thursday's meeting occurred shortly after the U.S. resumed some shipments of defensive weapons to Ukraine following a pause, ostensibly for the Pentagon to review domestic munitions stocks, that was cheered in Moscow. The resumption comes as Russia fires escalating air attacks on Ukraine and as Trump has become increasingly frustrated with Russian President Vladimir Putin. Rubio was also seeing other foreign ministers, including many whose countries face tariffs set to be imposed Aug. 1. Rubio sought to assuage concerns as he held group talks with ASEAN foreign ministers. "These engagements are very important to us, and we're going to continue to stay very committed because this, as I said to all of our partners, this notion or idea that the United States would ever be distracted by the Indo-Pacific or even Southeast Asia is impossible," he said. Trump notified several countries on Monday and Wednesday that they will face higher tariffs if they don’t make trade deals with the U.S. Among them are eight of ASEAN's 10 members. U.S. State Department officials said tariffs and trade won't be Rubio’s focus during the meetings, which Trump’s Republican administration hopes will prioritize maritime safety and security in the South China Sea, where China has become increasingly aggressive toward its small neighbors, as well as combating transnational crime. But Rubio may be hard-pressed to avoid the tariff issue that has vexed some of Washington's closest allies and partners in Asia, including Japan and South Korea and most members of ASEAN, which Trump says would face 25% tariffs if there is no deal.
