Washington ? Winding down his presidency, George W. Bush is beginning his farewell tour on the world stage trailed by questions about how much clout he still wields.

Unpopular abroad, as he is at home, Bush nevertheless has been a commanding presence among world leaders for the past seven years. Now, with fewer than 300 days left in his term, other presidents and prime ministers are looking beyond Bush to see who will occupy his chair a year from now.

It’s an open question whether Bush’s foreign policy priorities will be embraced by his successor in the Oval Office. Other world leaders have to calculate how far they should step out on the ledge with a president whose days are numbered and whose legacy had been darkened by the long and costly war in Iraq.

Air Force One will roar out of Andrews Air Force Base on Monday to whisk Bush to the first in a long-planned series of global goodbye events. After a brief stop in Ukraine, Bush stops in Romania to attend his last summit with NATO leaders.

A few days later, Bush will land in the Black Sea resort city of Sochi for his probable final meeting with Vladimir Putin as Russian president; his successor takes over in May.

Relations between Washington and Moscow have plummeted in recent years amid a welter of bitter disputes, and the talks in Sochi have raised hopes that Bush and Putin can lay the foundation for repairing ties.

This is the busiest travel year in Bush’s presidency in terms of the sheer number of trips.

He went to the Middle East in January and to Africa in February. After he returns from NATO and Russia, he has five more major excursions on the books – from Europe to Asia, the Middle East to South America.

In June, he will travel to Slovenia for his final summit with the European Union. He will attend his last summit of Group of Eight leaders of major industrial economies in Japan in July.

Around the world, there are hopes the next president will adopt a different style from what critics have called Bush’s cowboy diplomacy and go-it-alone foreign policy.

“There seems to be a great deal of enthusiasm, particularly for (Barack) Obama but also Hillary (Clinton) on the other side of the Atlantic, that there’s going to be some revitalization of the trans-Atlantic partnership and we start with a clean slate and a new chapter and all the rest,” said Julianne Smith, Europe program director for the Washington-based Center for Strategic and International Studies.
