TAIPEI: A Czech delegation led by its senate speaker is set to arrive in Taiwan later this month, Taipei said Thursday, following the highest-level US visit to the island that infuriated China.

Milos Vystrcil's delegation including the Prague mayor, the wife of late speaker Jaroslav Kubera and business leaders are scheduled to visit between August 30 and September 4, according to Taiwan's foreign ministry.

"The visit aims to highlight speaker Vystrcil's determination to uphold democracy and freedom, and that he would not succumb to the intimidation of authoritarian China," the ministry said in a statement.

Beijing views Taiwan as its own territory -- vowing to one day seize it -- and bristles at any moves by foreign governments to recognise or conduct official exchanges with Taipei.

China warned the United States not to "play with fire" on Wednesday as health chief Alex Azar wrapped up a three-day visit to Taiwan at a time of high tensions between Washington and Beijing.

The two powers have clashed over a range of issues from trade to military and the coronavirus pandemic.

Azar criticised China's handling of the pandemic and visited the makeshift shrine a former Taiwanese president hated by the Communist Party leadership during the highest-profile visit to Taiwan since Washington switched diplomatic recognition to Beijing in 1979.

Vystrcil is following in the footsteps of his predecessor Jaroslav Kubera, who died of a heart attack in January while planning the trip to Taiwan.

After Kubera's death, Czech media published a letter stamped by the Chinese embassy in Prague, in which Beijing threatened both Kubera and the Czech companies intending to accompany him on the trip.

Also on the upcoming delegation is Prague mayor Zdenek Hrib, who signed a partnership agreement with Taipei in January that sparked retaliation with Shanghai cutting their sister-city ties.
