BEIJING: China warned Wednesday that Washington would bear the consequences if US House Speaker Nancy Pelosi visits Taiwan, with tensions soaring ahead of an expected phone call between the two countries' leaders, reports AFP.
Beijing has hit back hard against the United States after reports emerged last week that Pelosi, a Democrat who is second in line to the presidency, could visit the self-ruled island of Taiwan in August.
Ties between the two global superpowers have continued to deteriorate under Biden's presidency, over issues including Taiwan, human rights and technology sector competition.
Beijing this week warned that it was getting ready for a possible visit by Pelosi, which would be the first to Taiwan by a sitting US House speaker since 1997.
We are firmly opposed to Speaker Pelosi's visit to Taiwan, Chinese foreign ministry spokesman Zhao Lijian said at a regular press conference Wednesday.
If the US pushes ahead and challenges China's bottom line... the US side will bear all the consequences, he added.
A possible visit by Pelosi -- yet to be confirmed by the senior Democrat -- has stirred alarm in Biden's administration, which fears the trip may cross red lines for China.
Last week Biden said the US military thought a visit was not a good idea right now.
Democratic Taiwan lives under constant threat of being invaded by China, which views it as part of its territory to be seized by force if necessary.
China's air incursions near Taiwan have risen sharply this year as Beijing works to isolate the island on the international stage.
Pelosi told reporters last week it was important for us to show support for Taiwan, while denying Congress was pushing for independence for the island.
In 1979 Washington switched relations from Taipei to Beijing, and successive administrations have been careful to recognise only one China by not sending top-ranking officials to Taiwan.
Washington has had a long-standing policy of strategic ambiguity on whether it would intervene militarily in the event of a Chinese attack on the island.
Biden recently said the United States was ready to defend Taiwan militarily in an invasion -- going beyond just providing weapons -- although the White House has walked back his remarks.
The US State Department in April approved the potential sale of equipment, training and other items to support Taiwan's Air Defense System in a deal valued at up to $95 million.
But Taiwan enjoys bipartisan backing in divided Washington and China's warnings have only fuelled calls for Pelosi to go ahead.
She has long been an outspoken critic of Beijing's human rights record, in 1991 outraging her hosts by unfurling a banner in Tiananmen Square in memory of pro-democracy demonstrators killed there two years earlier.
Taipei has said it welcomes visits from any friendly foreign guests and Premier Su Tseng-chang on Wednesday said Taiwan was very grateful to Speaker Pelosi for her support and friendliness... over the years.
A previous House speaker, Newt Gingrich, visited in 1997 but the Republican was from the rival party of the White House and Beijing's reaction was relatively muted.
CIA chief Bill Burns said last week that Xi appears committed to the option of using force against Taiwan, despite lessons from Russia's struggles in Ukraine.
I wouldn't underestimate President Xi's determination to assert China's control over Taiwan, he said.
