A largely processional race - "boring" according to Hamilton, who said he would "have been asleep on the couch" if watching at home - saw a virtual safety vehicle needed in the closing laps.
"It was a bit boring, the race", said Vettel. Both have won twice here - Vettel previous year and in 2011, Hamilton in 2016 and 2008, capitalising on the team error that scuppered Ricciardo.
Stoffel Vandoorne: "This was a disappointing race for me". It was a fearless move by the team but one that did not pay off as Vettel pitted four laps later and came back out in front of his championship rival.
"I wanted to close my eyes and start crying because I thought that was it, the race was over", he explained.
"OK mate, we can see what's going on", his race engineer replied after a pause.
His teammate complained of transmission problems, specifically downshift issues and rear-end lockup between second and third, and though no radio messages were heard at the time, Ricciardo later revealed he too had transmission problems and was driving with "just six gears" of his eight according to a post-race interview.
Watchdog: US-Chinese Agreement 'Does Nothing to Reduce Trade Deficit'
Negotiations are now behind closed doors, so it's unlikely we'll learn much more about this deal before it is settled. For months, Trump railed against China to cut its trade surplus with the United States and threatened higher tariffs.
Hamilton, who said the race was "the longest 78 laps ever", added in his BBC Sport interview: "It was a super-unexciting race for everyone".
Webber claimed Vettel was afforded preferential treatment by Red Bull's bosses, and although he has now patched up his relationship with the Ferrari driver, he rebuffed Vettel's claim that he would be keen to team up with Hamilton.
"He lost the MGU-K 17 or 18 laps into the race". The tyre temperatures start going up. But he kept his nose clean all afternoon, managed to recover a flat-spot, and pushed all the way to the flag.
"They're telling me on the intercom we're going to have to retire the auto in one or two laps". When asked whether the wider, higher downforce F1 cars are to blame for the lack of action, he said: "No, I think it's just Monaco". An imperious drive in qualifying has given him a commanding pole, and this race is his to squander.
"I don't think Seb would be in love with the idea".
Ricciardo was also fastest in all three practice sessions and the Australian driver will be confident of securing his second win after victory last month in China.
Ferrari's Sebastian Vettel - who finished second, and is a director of the Grand Prix Drivers' Association, which pushed for the switch to more durable tyres - refused to talk about the issue.
