Key NATO Summit to Open in Wales by VOA News World leaders are gathering Thursday in Wales for the start of a two-day NATO summit expected to focus on the conflict in Ukraine and the threat of Islamic extremists in Syria and Iraq. In the Welsh city of Newport, NATO is expected to debate formation of a rapid response military force capable of deploying on short notice to trouble spots in eastern Europe. Ukrainian President Petro Poroshenko is due to attend as a non-member invitee, and officials say he will meet with Western leaders on the sidelines of the gathering. Russia's foreign minister warned NATO not to offer Ukraine membership in the alliance and told the United States not to try to impose its will on the former Soviet republic. Sergei Lavrov also urged Kyiv and pro-Russian rebels fighting Ukrainian forces in eastern Ukraine to back peace moves outlined by President Vladimir Putin and avert what he said could be a large-scale crisis in the heart of Europe. Putin unveiled the seven-point plan on Wednesday. "It is precisely at such a moment when a chance has emerged to start solving specific problems between Kyiv and the militias that some sections of the Kyiv authorities make demands for Ukraine to drop its non-aligned status and start joining NATO," Lavrov said at talks with the Organization for Security and Cooperation in Europe, a rights and security group. "It's a blatant attempt to derail all efforts aimed at initiating a dialogue on ensuring national reconciliation." Underlining Moscow's concerns about U.S. influence on Kyiv, Lavrov added: "Some of our Western partners, including unfortunately the most influential players - the United States - want victory for NATO and a situation where America dictates its will to everyone." "This concept of exclusivity, which President Obama has repeatedly declared, can lead to no good and has so far led to no good," he said. Lavrov promised Russia would take "practical steps" to de-escalate the crisis in Ukraine and urged Kyiv and rebel leaders to accept Putin's proposals for a ceasefire. Also at the summit, NATO leaders are expected to discuss strategies for countering the threat from the Islamic State militant group that has overrun large parts of northern Iraq and eastern Syria. The U.S. has been carrying out airstrikes against the group in Iraq, while other alliance members have begun providing humanitarian aid. President Obama arrived late Wednesday at a British military base, following talks in the Estonian capital with the presidents of Estonia, Latvia and Lithuania. Speaking in Estonia's capital, Tallinn, the U.S. president condemned Russia's intervention in Ukraine as "a brazen assault" on a sovereign country. He sought to assure his Baltic counterparts that NATO will defend them against any possible Russian aggression. The three Baltic countries -- former Soviet republics -- joined NATO in 2004. Obama also announced plans to send more aircraft to the Baltics, and he said all NATO members must do their fair share of defense spending in order to bolster the alliance. He cited Estonia as an example of how all 28 NATO members must fulfill their pledges to contribute 2 percent of their gross domestic product to the alliance.
