China will protect the legitimate rights and interests of its companies after the inclusion of national companies in the US sanctions list against Cuba, warned Guo Jiakun, the spokesman of the Asian giant's foreign ministry. "The cooperation between China and Cuba is carried out in an open and honest manner. The Chinese side firmly opposes illegal unilateral sanctions and the so-called extraterritorial jurisdiction, which have no basis in international law and are not permitted by the UN Security Council," he emphasized, referring to the new steps of the US government. According to the diplomat, Beijing opposes Washington's attempts to interfere in the cooperation between China and Cuba and undermine the interaction between the two countries, and "firmly supports Cuba in the defense of its national sovereignty and its opposition to external interference."
