The Islamic State has already attracted an angry response from China after it executed a Chinese captive last week. Now the militant group, known as IS or ISIS, could rile Beijing again, this time by recognizing Taiwan as an independent nation.

In its latest propaganda video, ISIS lists the flags of countries it says are part of a global coalition against it. Among these is the Taiwanese flag. All the other flags are of sovereign nations.

Taiwan's Central News Agency linked ISIS's sudden recognition of Taiwan to a statement made by U.S. President Barack Obama at an Association of Southeast Asian Nations (ASEAN) summit in Malaysia last week. Obama said that Taiwan was one of the Asia-Pacific countries in a coalition against ISIS.

The Hong Kong Standard reported that SWAT teams were patrolling the Taiwan Taoyuan International Airport on Thursday after video prompted the Taiwanese government to step up security measures. Meanwhile, President Ma Ying-jeou urged the public not to panic.

Here is a screenshot from the video, which was posted on Wednesday.
