Heightened Chinese Coast Guard patrols in Taiwan Strait may impact East Asia shipping

There is a risk of heightened Chinese Coast Guard patrols off the Eastern Taiwanese coast in the Taiwan Strait that could impact shipping and trigger a national security threat to nations in East Asia, according to the Taiwan Strait Risk Report (TSRR) dated July 16, 2026.

The TSRR contains the following warning: “Taiwan Strait Risk Report will be raising its Taiwan Strait risk ratings virtually across the board. This reflects our assessment that China’s recent decision to routinize its coast guard patrols off the eastern Taiwanese coast will likely pave the way for a series of initiatives aimed at seriously limiting Taiwan’s access to the free flow of goods from crucial foreign suppliers – perhaps not immediately, but probably over the next 3-4 months.”

In an email to AJOT, Peter Enav, publisher of TSRR wrote that there is “the prospect of Chinese interference with shipping heading to Taiwanese ports.”

Iran War Diverts US

This is coming at a time when the Trump administration’s focus on the war with Iran has diverted US Navy assets to the Middle East and depleted stockpiles of munitions that places East Asian allies of the United States at risk if there is a conflict.

The TSRR explains Beijing’s reasoning: “Part of Beijing’s reasoning here, we believe, is that heightened tensions in and around the Taiwan Strait significantly bolster the prospects of the main opposition Nationalist Party in this November’s local elections, and even more critically, in the legislative and presidential polls set for January 2028. Given the Nationalists’ China-friendly bent, a good performance at the ballot box obviously raises the chances that Beijing will be able to realize its longstanding aim of taking Taiwan over without resorting to force – always assuming of course, that the newly elected Nationalist leadership retains its already well-documented China-friendly policies. This having been said though, a number of factors could still emerge to mitigate China’s willingness to substantially raise military and political tensions in the Taiwan Strait.”

Mitigating Factors

• “An assessment by the Chinese leadership that its wide-ranging purge of senior People’s Liberation Army officers has weakened the Chinese military to the point where it can no longer be counted on to deal successfully with possible armed American opposition to Chinese initiatives in the Strait. At least for now, there is little or no evidence that such an assessment has been made, or indeed, that is soon about to be made.”
• ” The Trump administration’s incontestable Taiwan skeptical worldview … has almost certainly heightened Chinese confidence that America is extremely unlikely to become militarily involved on Taipei’s side in any future Taiwan Strait conflict. “
• “Substantial reverses to the Chinese economy, leading to widespread civil discontent. Once again, it is our assessment that this is not yet on the cards, even allowing for the relatively low economic growth rates that China is now experiencing.”

The report notes, however, that “… virtually alone among the leading Asian economies, China has come out of the Iran War relatively unscathed, largely because it has stockpiled large reserves of hydrocarbons, and at the same time, gone a long ways to shield itself from the worst effects of hydrocarbon shortages by successfully executing the difficult transition away from crippling hydrocarbon dependence.”
