U.S. Secretary of State Antony Blinken accused China of taking “irresponsible acts” by cutting off vital lines of contact with Washington. He also claimed that China’s actions regarding Taiwan demonstrated a shift away from diplomatic resolution and toward the use of force.

As part of a number of measures taken by Beijing in response to a visit by U.S. House Speaker Nancy Pelosi earlier this week, island officials stated that he made his remarks as Chinese planes and warships practiced an attack on Taiwan on Saturday.

China’s retaliation in stopping bilateral processes in eight key areas including defence, narcotics, transnational crime and climate change were moves that would punish the world, not just the United States, Blinken told a news conference in Manila.

“Those include several military to military channels, which are vital for avoiding miscommunication and avoid crisis,” he said.

“Suspending climate cooperation doesn’t punish the United States, it punishes the world, particularly the developing world. We should not hold hostage cooperation on matters of global concern because of differences between our two countries.”

Tackling climate change has been a key area of cooperation between the two superpowers and two biggest emitters of greenhouse gas emissions.

Blinken said the United States had been hearing concern from allies about what he called China’s dangerous and destabilising actions around Taiwan, but Washington would remain steady in its handling of the situation.

He said he had conveyed to China’s Foreign Minister Wang Yi at a regional meeting in Cambodia that the United States was determined to keep communication channels going to prevent miscalculations, as countries around the world expected them to.

“So let me be clear, the United States doesn’t believe that it’s in the interest of Taiwan, the region, or our own national security to escalate the situation,” he said.

“We’ll keep our channels of communication with China open, with the intent of avoiding escalation due to misunderstanding or miscommunication.”

He added: “Maintaining dialogue is arguably even more important when we’re in a period of heightened tensions … We seek to deescalate those tensions. And we think dialogue is a very important element of that.”
