A Boeing jet set to be delivered to Xiamen Airlines in China was returned to the U.S. amid a growing trade war between the two nations.

Boeing jet intended for use by a Chinese airline was heading back to the U.S. on Monday, flight tracking data showed, in what appeared to be another victim of the tit-for-tat bilateral tariffs launched by President Donald Trump in his global trade offensive.

Boeing has brought back two 737 MAX 8 aircraft from its 737 Completion and Delivery Center in Zhoushan, China, amid an ever-escalating trade war between China and the United States, with the latter country putting an up to 245% tariff on the former.
