US President Donald Trump has signed legislation that would allow US officials to travel to Taiwan to conduct so-called official exchanges. The White House says the bill will go into effect Saturday morning. China has been swift to condemn the move by Washington, urging the United States to abide by the One China Policy. Chinese Foreign Ministry spokesperson Lu Kang also reiterated that Beijing opposes the legislation. The move further strains relations between the two countries, following Trump's import tariffs, and his call for China to reduce its trade imbalance with the United States.
