The United States welcomed China's growing role in trying to ensure Afghanistan's stability on Thursday, saying a Beijing conference of foreign ministers on Afghan reconstruction this week shows its commitment to the region as Western troops pull out.

The comments, made by a senior State Department official, are rare U.S. praise for Beijing, which this week hosts Afghan President Ashraf Ghani on his first visit abroad since assuming office in September.

Washington and Beijing, which have typically contentious relations on geopolitical issues from Iran to the South China Sea, have both said they see Afghanistan as a point where their security interests converge.

On Tuesday, China pledged to give Afghanistan $327 million in aid through 2017, more than the $250 million contribution it has so far offered since the fall of the Taliban regime in 2001.

"China's view of engaging in Afghanistan over the course of these past few years has really changed significantly, and in our view, in a very positive direction," the official told reporters during a telephone briefing.

On Friday, foreign ministers from Asian and Central Asian countries will gather in Beijing for a fourth round "Istanbul Process" conference on Afghanistan, which China hopes will help boost development and security there. White House counsellor John Podesta will attend the meeting.

"It's a real demonstration of China's commitment to Afghanistan, to its role in the region and one that we greatly welcome," the official said.

Additional support on counter-terrorism "would be very valuable", the official said, noting that improving coordination on "terror-finance" issues at the United Nations would be an area of U.S.-China discussion in the future.

China, connected to Afghanistan by a narrow, almost impassable mountain corridor, has been preparing for more responsibility in Afghanistan after the bulk of U.S.-led troops pull out this year.

It says it does not seek to fill a void left by the U.S. withdrawal but has promised to play a big commercial role in reconstruction.
