Vladimir Putin urges co-operation in new year message to Barack Obama
Russian President Vladimir Putin has used his new year message to US counterpart Barack Obama to call for co-operation between their countries to respond to international challenges.
Ties between Moscow and Washington reached a post-Cold War low when Russia annexed Ukraine's Crimean peninsula and threw its support behind separatist rebels in eastern Ukraine.
The US and other nations responded with economic sanctions against Russian officials, state-owned companies and entire sections of the economy.
The Kremlin on Wednesday quoted Mr Putin's new year greetings to Mr Obama as saying the "relations between Russia and the United States are crucial to ensuring global security".
Mr Putin was also quoted as saying that both countries would "successfully take on new challenges and threats" across the world if they were to engage in a "constructive dialogue".
