Kabul, Afghanistan (CNN) -- The United States has made "significant progress" in combating terrorist threats to the border region of Afghanistan and Pakistan, Homeland Security Secretary Janet Napolitano said Saturday after meeting with the Afghan president and the minister of finance.
Napolitano is in Afghanistan to discuss progress made in securing the region.
"The Obama administration remains fully committed to combating threats of terrorism in Afghanistan," Napolitano said in a statement released Saturday.
In her meetings with President Hamid Karzai and Minister of Finance Mohammad Omer Zakhiwal, Napolitano also discussed the Department of Homeland Security's efforts to combat the trafficking of chemicals used to manufacture improvised explosive devices and the department's ongoing efforts to expand border protection training and guidance to the Afghan government.
Napolitano also held a round-table discussion with Afghan women and U.S. women serving in the region. During the discussion, she reiterated President Obama's commitment to advancing the rights of women and girls in Afghanistan.
On Friday, Napolitano toured border security operations at Torkham Border Crossing. She spent New Year's Eve with U.S. troops in the region.
She also reviewed security operations at a key point along the Pakistani border -- part of an ongoing U.S. effort to strengthen Afghanistan's border police.
Napolitano is scheduled to meet with a number of senior U.S. and Afghan officials during her visit -- part of a week-long trip that also includes stops in Qatar, Israel and Belgium.
Six U.S. border security and customs officers are traveling with Napolitano, an earlier statement said.
Recent U.S.-led training efforts in Afghanistan have focused on stopping bulk cash smuggling and shipments of ammonium nitrate, according to a November statement released by the State Department.
