The Taiwan Travel Act will harm both China’s relations with the US and with Taiwan. It may also forfeit the possibility of peaceful reunification.

Here’s what China and the US should do to move their relationship forward.

The United States has revamped its maritime response to Chinese policy in the South China Sea, conducting its first Freedom of Navigation Operation (FONOP) since President Trump took office. While China cannot allow this action to go unchecked, it should consider its larger global and regional power objectives before determining its response.

The U.S. House of Representative passed the National Defense Authorization Act (NDAA), a provision that allows for mutual stationing by military vessels between the United States and Taiwan. The President should veto the Act in the interest of smoothing the development of China-U.S. relations along with his own foreign policy agenda.

The worsening relations between the mainland and Taiwan place the United States in an awkward and potentially dangerous position. Washington should retain the right to sell weapons to Taipei so the Taiwanese can deter an attack from the mainland, or if deterrence fails, have a decent chance of repelling such an attack. Conversely, the United States must make it clear to the Taiwanese leadership that, fond as we might be of democratic Taiwan, America will not risk war with China to protect the island and preserve its de facto independence.

While issues in bilateral economic relations and trade are negotiable, the one-China policy is not. The Trump administration should carefully sum up the lessons of previous administrations on the Taiwan question and minimize its impact on overall China-US relations so that steady progress can be made, especially in economic relations and trade, which bring tangible benefits to both sides.

Despite US remarks that have energized supporters of Taiwan “independence”, the US is in no position to abandon the one-China policy and has no real plan to do so. For the sake of the healthy development of Sino-US relations, the US should stop all its official contacts and exchanges with Taiwan, reducing its arms sales to Taiwan, and move toward a final resolution of this lingering sore spot.

If the DPP continues to create obstacles for cross-straits relations out of its selfish partisan interests, there is ample reason for us to feel concerned about the state of mainland-Taiwan relations in the next three years.

The inauguration of President Donald J. Trump on January 20, 2017 suggests that U.S. foreign policy is moving away from the Wilsonian liberal internationalism, which has guided American foreign policymaking since the end of World War II, toward the “America-first” Jacksonian populism.
