KUALA LUMPUR - US President Barack Obama told Russia Sunday it should cooperate with international observers in Ukraine, not stand by while they were detained by pro-Moscow "thugs." Obama also made his first public comments on new international sanctions due to come into force early in the week against Russia, saying they were a punishment for Moscow's "provocation" in eastern Ukraine.
Obama weighed in on the deepening crisis from Malaysia after a group of Organisation for Security and Cooperation (OSCE) observers were detained by pro-Moscow rebels who branded them spies.
He said that among steps Russia should take was to work with "international observers rather than stand by while they are being bullied and in some cases detained by these thugs." The observers were seized by rebels in the flashpoint town of Slavyansk which is under siege by the Ukrainian military.
Obama said that the new sanctions being drawn up by G7 countries were a new sign to Russia that it must embrace a diplomatic solution to the crisis, following the failure of the Geneva agreement designed to reduce tensions.
"It is important for us to take further steps sending a message to Russia that these kinds of destabilising activities taking place in Ukraine have to stop," Obama said.
Obama spoke a day after G7 nations said that they would impose new sanctions on Russia within days, accusing Moscow of doing nothing to honour an agreement forged in Geneva aimed at easing tensions in Ukraine.
"So long as Russia continues down a path of provocation rather than trying to resolve this issue peacefully and de-escalate it, there are going to be consequences and those consequences will continue to grow," Obama said.
He also defended his decision to wait for European partners - which have far more exposure to Russian trade and investment than the United States - before unveiling another set of sanctions.
"The more we are united, the more effective it is going to be," Obama said.
US officials say the next set of sanctions will target key officials in the energy and banking sectors who they say are "cronies" with significant influence on Russian President Vladimir Putin.
