News - Middle East: US House of Representatives speaker Nancy Pelosi has started her visit to four Asian countries without mentioning Taiwan, as tensions rise over the self-ruled island.

“Speaker Nancy Pelosi is leading a Congressional delegation to the Indo-Pacific region, including visits to Singapore, Malaysia, South Korea and Japan,” her office said in a press release on Sunday.

“The trip will focus on mutual security, economic partnership and democratic governance in the Indo-Pacific region,” the release said.

Pelosi, who is President Joe Biden’s equal in rank as leader of one of the three branches of government, would be the highest ranking US politician to travel to the island since 1997.

She has so far declined to discuss the details of her trip, but said last week that it was “important for us to show support for Taiwan.”

Meanwhile, China has warned the United States that it would be responsible for any consequences of a visit to Taipei.

Biden administration officials have reportedly expressed concerns that China may try to impose a no-fly zone over Taiwan ahead of the visit.
