Here is video of Robert Gibbs being asked about President Obama delaying his meeting with the Dalai Lama.
Gibbs was asked "is he (Obama) worried about irritating Chinese leaders before his visit?" Gibbs answered "there was an agreement to do this later in the year, and that is what's going to happen." Gibbs also said "it's important that the Tibetan people know our relationship with China helps them." He was then asked "what does meeting with the Dalai Lama later have to do with leading a strong relationship with China?" Gibbs struggled a bit to answer that.
