The announcement, not immediately confirmed by Washington or Islamabad, comes as America's chief negotiator tours the globe shoring up support for a peace process to end its longest war.

Zalmay Khalilzad, a former ambassador to Afghanistan, held extensive talks with the militants last month in Qatar, where the Taliban have an office. More talks are slated for later in February.

But a Taliban statement issued Wednesday said separate meetings would be held first on February 18 in Islamabad "by the formal invitation of the government of Pakistan".

Talks in Doha would follow a week later on February 25, the statement said.

Khalilzad is heading a large delegation on a tour of Belgium, Germany, Turkey, Qatar, Afghanistan and Pakistan to boost the peace process and bring all Afghan parties to the table.

He has expressed cautious hope for a deal before Afghan presidential elections slated for July, but says the Taliban must come to the table with the Kabul government, which the insurgents consider a US puppet.

President Ashraf Ghani -- who has expressed frustration at being sidelined from recent talks -- flew to Munich on Wednesday to attend an international security conference, his office said.

The Taliban also announced a meeting with Prime Minister Khan in Islamabad for "comprehensive discussions" about bilateral affairs with Afghanistan.

News reports in Pakistan last month had suggested Islamabad was open to hosting the next round of talks with the insurgents.

In January, as he travelled the region building support for the peace process, Khalilzad met Khan in Pakistan -- one of just three countries that recognised the Taliban regime before their ousting by US-led forces in 2001.

Pakistan's foreign ministry said in December that President Donald Trump, who is pushing to end the 17-year war in Afghanistan, wrote to Khan seeking Islamabad's support for peace efforts.

Ties between Washington and Islamabad have soured recently.

US officials have repeatedly accusing Pakistan of turning a blind eye to, or even collaborating with, the Afghan Taliban, which launch attacks in Afghanistan from alleged havens along the border between the two countries.

The White House believes that Pakistan's Inter-Services Intelligence agency and other military bodies have long helped fund and arm the Taliban, and believe a Pakistani crackdown on the militants could be pivotal in deciding the outcome of the war.

Pakistan has long denied the claims, saying thousands of its citizens have been killed in its long struggle with militancy.
