China had previously cut off oil to North Korea temporarily for a few days.

"But amid fears of the hermit kingdom’s instability, the measure isn’t likely to be permanent."
In late November 2017, China's special envoy to North Korea spent four days without being able to meet Kim Jong Un.
The US is bending backwards. Secretary of State Tillerson has said the US is willing to talk to North Korea without preconditions.
There are reports that China is preparing refugee camps along the North Korean border.
The US has assured China that the US military will pull back to the 38th parallel after a North Korean invasion.
Where does that leave us today?
North Korea won't talk to China.
If North Korea also won't talk to the United States then talking is a dead-end.
US President Donald Trump will not accept the status quo. He needs a "win" for his re-election campaign. It is incredibly dangerous when a US president is weak at home (e.g. Russia-Trump investigation by Special Counsel Mueller) and he needs a big foreign policy win.
China is NOT going to send tens of thousands of Chinese soldiers to their deaths to defend an obnoxious and inflexible Kim Jong Un.
That means the US will eventually invade North Korea. The US foots the military costs. China pays for the humanitarian costs. North Korea is stabilized after Kim is removed. Everybody goes back to business as usual.
Do you see another reasonable outcome? I don't.

As a reminder, during the Korean War (1950-1953), UN troops led by the US crossed the 38th parallel on October 1, 1950.
On October 18 1950, China ordered 200,000 troops into North Korea which occurred on October 25 1950.
"On 25 November at the Korean western front, the PVA 13th Army Group attacked and overran the ROK II Corps at the Battle of the Ch'ongch'on River, and then inflicted heavy losses on the US 2nd Infantry Division on the UN forces' right flank.[204] The UN Command retreated; the U.S. Eighth Army's retreat (the longest in US Army history)[205] was made possible because of the Turkish Brigade's successful, but very costly, rear-guard delaying action near Kunuri that slowed the PVA attack for two days (27–29 November). On 27 November at the Korean eastern front, a U.S. 7th Infantry Division Regimental Combat Team (3,000 soldiers) and the U.S. 1st Marine Division (12,000–15,000 marines) were unprepared for the PVA 9th Army Group's three-pronged encirclement tactics at the Battle of Chosin Reservoir, but escaped under Air Force and X Corps support fire—albeit with some 15,000 collective casualties.[206]
By 30 November, the PVA 13th Army Group managed to expel the U.S. Eighth Army from northwest Korea. Retreating from the north faster than they had counter-invaded, the Eighth Army crossed the 38th parallel border in mid December.[207] UN morale hit rock bottom when commanding General Walton Walker of the U.S. Eighth Army was killed on 23 December 1950 in an automobile accident.[208] In northeast Korea by 11 December, the U.S. X Corps managed to cripple[209] the PVA 9th Army Group while establishing a defensive perimeter at the port city of Hungnam. The X Corps were forced to evacuate by 24 December in order to reinforce the badly depleted U.S. Eighth Army to the south.[210][211]"
When you look at the Korean War timeline, the US had two months (October 1 1950-November 25 1950) to return to the 38th parallel. If the US had done so, China would not have intervened in the Korean War.
