The nine-point lead enjoyed by Sebastian Vettel after his controversial victory in Malaysia is down to just three after China following Kimi Raikkonen's second place finish.
While the results remain provisional pending a series of possible punishments for use of DRS under yellow flag conditions, Raikkonen's drive to the podium with a broken front wing and nose maintained his scoring record for 2013, taking his tally to 49 points, just three adrift of Vettel, who narrowly failed to deprive Lewis Hamilton of third spot.
Hamilton now sits in fourth spot, twelve points off the lead, while Shanghai racewinner Fernando Alonso moves ahead of his former team-mate into third overall, with 43 points.
The luckless Mark Webber, who started the day in third overall, now sits sixth after failing to finish, slipping behind the second Ferrari of Felipe Massa, while Jenson Button's run to fifth place earns him a share of seventh with Nico Rosberg, who also posted a DNF.
In the constructors' standings, Red Bull continues to lead, but now has just a five-point cushion over Ferrari, while Lotus is third overall, eight points ahead of Mercedes, with McLaren and Force India well adrift in a share of fifth.
