"We've had a better start than we expected and to have finished in fifth and third places so far is really positive," said Hamilton. "I know there is much more to come ..."
Champions Red Bull will be the focus of much of the media attention, despite Vettel apologizing to the team and to Webber after the Malaysian race.
Team principal Christian Horner has said the matter has now been dealt with, and Red Bull's unusually bland race preview made no mention of the controversy, but it is sure to be simmering still.
Webber, but not Vettel, has been listed for Thursday's regular FIA news conference at the circuit which will give the Australian a platform to get any lingering grievances off his chest, even if the initial fury has subsided.
McLaren, which has won three times in China, is looking for a marked improvement after two disappointing opening races that have left 2009 champion Jenson Button with just two points.
"In a funny way, the Chinese Grand Prix almost feels like something of a reboot of the start of my season," said Button, whose China memories run the gamut from victory in 2010 to embarrassment in 2011 when he pulled in at the Red Bull garage instead of McLaren's.
"I think everybody in the team has picked themselves up and really attacked the task of addressing our car's issues," said the Briton. "We know where we're losing performance so I think we're actually all looking forward to seeing just what we can achieve."
Ferrari's Fernando Alonso will be keen to get his championship campaign back on track after crashing out in Malaysia while Kimi Raikkonen is another force to reckon with in the Lotus.
Memories of China may also play on Adrian Sutil's mind, although the Force India driver would rather forget them as he makes his return for the first time since a 2011 night club brawl in Shanghai almost ended the German's career.
The German, handed a suspended jail sentence and fined, was dropped by the team for the 2012 season before making a comeback this year.
