Prime Minister Ehud Olmert advised the ministers at Sunday's cabinet meeting not to relate to the Baker-Hamilton report, presented last week in the US, which called for Israel to hold talks with Syria.
"We must refrain from comments that bring us into the internal conflicts in the US," Olmert said.
The prime minister noted that the only such comment that had been made on the subject was when he had said that Bush had no intentions of speaking with Syria and Iran.
"My saying this was no coincidence," he said. "I don't recommend that you speak about this, but if someone feels the need to do so, please coordinate it with my office so conflicting statements won't be heard from the government."
