The White House said Friday that President Donald Trump will not meet formally with Russian President Vladimir Putin at an Asia-Pacific summit in Vietnam this week due to a scheduling conflict, according to Bloomberg financial data and media company.

Earlier, the Kremlin had announced that both sides were working on a suitable time and format for a meeting when both men are in Vietnam. But US Secretary of State Rex Tillerson had downplayed this possibility saying there was no point meeting if there was not the likelihood they would make progress on a number of issues.

Bloomberg noted that, “Any Putin-Trump meeting would be fraught with political complications for Trump, as his campaign and his administration face investigations over ties to the Russian government during the 2016 [US] presidential campaign.”
