Whoever wins in Tuesday's presidential election will have to tip more toward dialogue and diplomacy in an increasingly globalized world that is being inflicted with all kinds of complex issues like war, economic crisis and etc, a U.S. expert said Monday.

Starting from his first day of presidency, the new president will have to deal with wide-ranging issues both domestically and internationally, and it would serve the American people and the world better if he could seek to do so through cooperation instead of threatening wars, said Greg Payne, a political science professor in Boston-based Emerson College, in an interview with Xinhua.

"The world is a global village. We have to deal with the Palestinian-Israeli issue, the Syrian issue and etc. But is it going to be more dialogue, more diplomacy, or is it to call the Pentagon to get ready for a war on a credit card that we have already put on two wars. I don't think that credit card can take it," said Payne, an expert and educator in fields including political communication, public diplomacy and crisis communication.

U.S. voters will go to the polls on Tuesday to make a decision between incumbent President Barack Obama and Republican candidate Mitt Romney. The winner could be announced on Wednesday and the new president will take office early next year.

In terms of foreign policy, Obama is in a better position to fare well if he gets re-elected, he said. "Obama is a more sophisticated global politician. The president is much more deliberate. First of all, he has an understanding of the world."

Romney, on the other hand, does not have a clear-cut foreign policy as far as what he has said during the campaign is taken into account, Payne said.

"I thinks he is a very good CEO and I think he makes choices as governor," he said. "One thing I really have no idea is what will his foreign policy be."

Judged from what Romney has said, he "sounds a bit like George W. Bush, which was problematic" especially when he lets neoconservatives like former vice president Dick Cheney be around him, said Payne, who is also the funding director of the Saudi American Exchange, the first grass roots public diplomacy effort in the wake of 9/11. The project was honored at the inaugural Clinton Global Initiative, which was established in 2005 by former U.S. President Bill Clinton to convene global leaders to explore solutions to the world's most pressing challenges.

"The Mitt Romney I would respect would say that 'ok, we can't go down that road again', Payne said.

Besides, Romney has been ambiguous on where he stands in foreign policy in terms of dealing with the issues of Iran and Syria and he even did not sound so much different from the policies being pursued by the Obama administration.

In his third debate with Obama, Romney did not specify what his policy would be. Instead, he kept on saying that "I agree with the president." "He had more agreements with the president in that third debate than (Vice President) Joe Biden did. It was almost like that maybe you should be the VP," Payne said.

On the most recent China-bashing tactics being employed by both campaigns, Payne said that all these moves that unfairly used China as a "devil figure" were made as "part of the game," which will be expected to go away as soon as the election is over.

"My response is that we live in a global village. China needs us. We need China. We need good relations with China," he added.
