And the former double world champion, who has won the past two races, says he would love nothing more than to deprive Hamilton of the chance of a first world title.
"You can be here forever, and you cannot misunderstand what I said," he told autosport.com about last week's comments. "When we say all these things, my best relationship is with Robert and I would like to see him win the championship.
"But it is quite difficult because the performance of his car means it will be difficult to recover 12 points. But I will do my own job but when you see the results you prefer some teams to win or some teams to win compared to others.
"I will not be any key part to the championship, whatever driver wins will win because he did a better job in the last two races. You can take whatever you want from my comment but it is very simple."
After winning the last two Grands Prix, Alonso has set his sights on a hat-trick and the Spaniard is confident his Renault car is well enough equipped to succeed.
"Hopefully we can do well here [in China], he added.
"Obviously the victories are always... I am still thinking we are not as quick as maybe the contender for the win here, but we can do a good job again and take hopefully many points for the team.
"The car is really nice to drive now, the last month and a half, so I don't see any reason why here will not be a competitive car. Maybe not for a win but hopefully the podium will be our target."
