US Defence Secretary Leon Panetta will meet Defence Minister A K Antony today where the two sides are expected to discuss the entire gamut of their strategic and military relationship and the situation in the Af-Pak region.

"During the meeting, the ongoing defence cooperation and regional security situation will figure prominently," the defence ministry said in a release.  

China is also expected to figure in the discussions between the two countries.  Panetta may express America's desire to team with India on security. Pakistan's role in Afghanistan may also come up for discussion, say sources.  

Panetta arrived in India Tuesday on a two-day visit.
