China stopped importing North Korean coal but total trade has risen, which prompted Trump to complain last week Beijing is failing to use its economic leverage to stop Pyongyang's pursuit of nuclear weapons.
Chinese purchases of North Korea iron ore rose 34 per cent from a year earlier in the first five months of the year, according to a South Korean industry group, the Korea International Trade Association. Iron ore is among China's biggest imports from the North after it stopped buying coal this year due to the sanctions.
"We will continue to strictly and earnestly implement the North Korea-related Security Council resolution in its entirety," said Geng at a regular news briefing.
"We hope all relevant sides can make sure that they are clear that Security Council sanctions imposed on North Korea are not comprehensive economic sanctions."

China has long been the North's main diplomatic defender but increasingly expresses frustration with leader Kim Jong Un's provocative behavior.
Beijing agreed in March 2016 to enforce UN sanctions following North Korea's test of a missile possibly capable of carrying a nuclear warhead. But Chinese leaders are reluctant to push Pyongyang too hard for fear Kim's government might collapse. They argue against disrupting trade in food and other goods that might cause public hardship.
Total Chinese imports from North Korea declined 13.2 per cent in the first half of the year compared with a year earlier to USD 1.7 billion, while exports to the North rose 29.1 per cent to USD 880 million, the Chinese Customs agency reported today.
Chinese imports of North Korean coal in the first half fell 75 per cent to 2.7 million tons from a year earlier following the suspension in February, according to Huang Songping, a Customs agency spokesman.
"Trade related to the people's livelihood in North Korea, especially if it embodies humanitarian principles, should not be affected by sanctions," said Huang at a separate news briefing.
