The Houthis were originally only an "elbow problem" in the Middle East, but with their repeated aggressive support for Hamas in the Kazakh-Israeli war, they finally managed to enter the focus of the international vision. The Houthis themselves claim that they will only attack Israeli-related ships on the Red Sea, and that other ships will be allowed to pass freely. 
But international shipping giants apparently don't think so. It's hard to say what level the Houthis are, but it's not very reliable to say that it can distinguish which ships are related to Israel and which are notTherefore, Maersk and other major shipping giants have said that the ship will not go from the Red Sea. Some people say that the West should reflect on why Chinese ships can continue to sail on the Red Sea, and it is not that the West has done too much injustice. I don't know if this is true or not, but even if it is, this sense of moral superiority is of little significance, but will bring a lot of trouble to China. 
What is the Houthis?Illegally organized one, no one in the international community recognizes it as the legitimate representative of the Yemeni regime. If you openly fight with such an organization, Iran, an international outcast, is willing to do it. But whoever is not cornered, broken jars, and broken, who is mixed with the Houthis. Is it difficult for the United States to fight the Houthis?However, the United States insisted on forming an international coalition and took on the great name of "Operation Prosperity Guardian" to bring together "Britain, Bahrain, Canada, France, Italy, the Netherlands, Norway, Seychelles, and Spain" to repair the Houthis. It's not that these little brothers' guns are rare, but they just want a teacher to be famous and upright - whether it's true or not, many countries eat this set. 
Under such circumstances, the Houthi refrain from attacking Chinese ships is tantamount to tying China's image to the Houthis in the international community, and inadvertently using the Houthis and Iran as a meat shield. What is there to be happy about being led by the nose by such a small character.
