Rome, November 7 - President Barack Obama is "nice to work with," Italian Premier Mario Monti said on Wednesday following the Democratic candidate's re-election. Premier Monti underlined the crucial role of the US president in and out of the country. "President Obama knows how to use the tools of the market and of the State. As a president he is attentive to the needs of the U.S., but also understands Europe. That is important for us," Monti said. Monti told reporters that he had congratulated Obama on his hard-earned success and the battle for re-election that ended in the "spirit of national unity that characterizes America". Italy is counting on a "strong" United States to continue to play a lead role on the international stage, Monti said in his message of congratulation to Obama on Wednesday. "With your confirmation in the White House, Italy knows that it can count on a strong, supportive America that will continue to play a fundamental role on the international scene and commit itself to addressing the many global challenges," Monti said in the message, "ensuring international peace and security, responding to the legitimate yearning for liberty of the many countries that are looking to democracy and, finally, overcoming the difficult economic situation". Monti also said in the message to Obama that he looked forward "with pleasure to the continuation of cooperation between us, based on the special harmony that has developed at the personal level and between our two governments". Europe still has work to do to "accelerate growth and create a more unified political situation," premier Monti said. However, Monti also said that the United States "still has some work to do" to strengthen its financial discipline.
