"China opposes the application of extraterritorial jurisdiction and unilateral sanctions based on the domestic laws of this or that country … We call on the United States to stop such illegal actions in order to avoid damaging bilateral cooperation on relevant issues," Geng stressed.
He underlined that China respected all UN resolutions on North Korea.
"China strictly and fully complies with all UN resolutions on the DPRK [North Korea]. If any Chinese companies or individuals violate the relevant resolutions, each of these cases will be considered in accordance with Chinese law," the diplomat added.
The Treasury Department said in its release that Dalian Haibo violated the sanctions by providing goods and services to North Korea's Paeksol Trading company, while Liaoning Danxing used deceptive shipping practices that enabled North Korean procurement officials based in Europe to purchase goods.
