China has preferred to let other governments take the public lead in resisting U.S. pressure for new sanctions on Iran. At times Germany and Russia have served that purpose. So, President Hu Jintao was happy to let Brazilian President Luiz Inacio Lula da Silva denounce sanctions after their private meeting on the sidelines of the BRIC (Brazil, Russia, India, China) summit in Brasilia last week. President Lula had told President Barack Obama personally of Brazil's position earlier in the week at the Nuclear Security Summit in Washington. President Hu said nothing about Iran, but merely smiled like a Cheshire cat as Brazilian officials said their country had an "affinity" with China on the Iran issue. Brazil currently holds one of the rotating seats on the UN Security Council.
