Poland agrees military cooperation with non-NATO Sweden
Warsaw, Sept 14, 2015 (AFP) -- NATO member Poland on Monday signed a deal on military cooperation with non-member Sweden amid concerns raised by increased Russian military activity in the Baltic.
"Once a sea of peace, the Baltic has become a sea of danger," Polish Defence Minister Tomasz Siemoniak told reporters at a joint press conference in Warsaw with Swedish counterpart Peter Hultqvist.
Hultqvist said the increased presence of Russian warships and warplanes in the Baltic Sea had prompted Stockholm to take "two strategic decisions".
One was to boost defence spending by 11 percent over five year, and the other was to reinforce cooperation with NATO as a whole, as well as with its individual members.
Sweden's foreign ministry on Friday summoned Russia's ambassador after Moscow threatened "retaliatory measures" if the Scandinavian country joined NATO.
The increased tensions come on the heels of Russia's 2014 annexation of Ukraine's Crimean peninsula and backing of separatist forces in the country's east.
President Petro Poroshenko commented on the possibility of appointing Mikheil Saakashvili, currently Odesa governor, as Ukrainian prime minister. A petition asking the president to appoint Saakashvili as the head of the government has collected more than 31,000 signatures online.
"He will be a great prime minister. In Georgia. As for our country, we already have a government," Poroshenko said in an interview with the German newspaper Die Welt.
According to the new amendment to Ukrainian law, the president has to respond to all electronic petitions that gain more than 25,000 supporters online.
