BEIJING, November 10 /TASS/. Russian President Vladimir Putin and US President Barack Obama have greeted each other on the sidelines of the 2014 APEC summit but no serious conversation has taken place between them.

“There was no conversation. They really greeted each other - it was that brief contact on the sidelines of the event that we had discussed,” Putin’s press secretary Dmitry Peskov told journalists on Monday.

Peskov said the presidents assume they will get a chance of having a conversation in the coming days.

A representative of the US presidential administration confirmed that the two presidents had a brief conversation, noting they didn't have time to discuss any controversial matters. She didn't rule out that the presidents may have a more substantial conversation on tuesday.

After a reception in honour of the participants of the forum, China’s President Xi Jinping invited his guests outside to watch a massive fireworks show that lasted for about 20 minutes. Different coloured fantastic fireworks illuminated the sky over the city making it as bright as in a sunny day. Pyrotechnicians even managed to write the lines APEC-2014 in the sky. A part of the show was accompanied by music.
