Of course it's not

AFP has an article about moving the detainees, or some of them:

Palau's president Johnson Toribiong said his country's decision to take in up to seventeen Chinese Uighur detainees currently held at Guantanamo was not linked to the upcoming review of US aid to the tiny Pacific nation. Toribiong earlier announced his country of 21,000 people would accept the Muslim detainees temporarily as a "humanitarian gesture".
He told local reporters late Wednesday that the decision was not linked to the review of aid under the Compact of Free Association between Palau and the US, which administered the UN Trust Territory until independence in 1994. "When we talked to the US representative, we were on the same understanding that this is not linked to the Compact review," Toribiong said. "We took this seemingly radical position (to accept the detainees) at the time the Compact review is ongoing, but it is not linked," he said.
In Washington, State Department spokesman Ian Kelly also denied any link between US aid and the transfer of the Uighurs. Toribiong said earlier the decision to accept the detainees was "a humanitarian gesture intended to help them be freed from any further unnecessary incarceration." The seventeen were among a group detained during US-led military operations in Afghanistan and transferred to Guantanamo Bay in Cuba.
US authorities cleared the Uighur detainees of wrongdoing four years ago, saying they only had a camp in Afghanistan. But they have been stuck in the controversial US detention camp because no one else would take them. Washington refused to hand them over to China, fearing they would be tortured. But US lawmakers shot down President Barack Obama's plans to resettle at least some of them in the United States, alleging they still posed a security risk.
Xinjiang, a vast area that borders Central Asia, has about 8.3 million Uighurs, and many members of the mostly Muslim community say they have for decades suffered under Chinese political and religious persecution.

Rico says he hopes the Uighurs like warm weather; Palau is even hotter than Cuba...
