US-Russia summit hoped to ease strain

US President Donald Trump and Russian President Vladimir Putin will tackle some thorny bilateral and regional issues on Monday in a summit that experts say might halt a further worsening of their relationship but won't make any breakthrough.

Trump and Putin plan to meet one-on-one at the start of their first formal summit in Helsinki, Finland, on Monday afternoon, before allowing their aides to participate.

The Finnish president's office said the leaders of the United States and Russia will meet at the 19th-century Presidential Palace, near the city's waterfront Market Square.
