Twitter will only censor tweets when it is legally required to do so, confirmed Twitter CEO Dick Costolo on Monday.

The comments come after a scare from a recent Twitter corporate blog post. The company said that because some countries have different ideas about “the contours of freedom of expression," Twitter would not be able to exist in those countries, Costolo told AllThingsD,

“There’s been no change in our stance or attitude or policy with respect to content on Twitter,” Costolo said, at the D: Dive into Media Conference.

Costolo said that the only change is that is to block tweets in the country issuing an order, as oppose to all users around the world.

“When we receive one of those, we want to leave the content up for as many people as possible while adhering to the local law,” Costolo said.

He claimed that this new policy is not about making entre into China or Iran, where Twitter is censored entirely.

“I don’t think the current environment in China is one in which we could operate,” Costolo said.

“It is simply not the case you can operate in these countries and choose which of the laws we want (to adhere to),” Costolo said.
