With the U.S. and Russia on opposing sides of the Syria crisis, one analyst says it is unlikely they will find common cause at G20.
World leaders arrive in Russia for the G20 summit.
They come as Syria has moved to the forefront of the international agenda -- with few signs of common cause.
Its no surprise says political analyst Konstantin Eggert.
"It's absolutely unrealistic to expect any practical decisions for example on the Syrian issue or on the problems of the global financial system when these 20 countries have obviously different or even conflicting interests," said politicsl analyst Konstantin Eggert.
Much of the focus has been on the US and Russia, who are on opposite sides of the Syrian conflict.
U.S. President Barack Obama is trying to rally Western support for military action against Syria over what Washington believes is the killing of 1,400 people in a chemical weapons attack.
Russian President Vladimir Putin wants Syria put on the G20 agenda and is unlikely to pull any punches.
"President (Vladimir) Putin doesn't like, or I would even put it stronger, despises president (Barack) Obama, sees him as an inexperienced politician, a person too much focused on his own public relations, who has too much trust in ratings and his spin-doctors, a person who has changed his Middle East policies twice in the last two years," Eggert said.
The conflict will be discussed on the sidelines of the summit but it is not clear whether it will be put to the leaders for formal discussion.
