After he arrived at Beijing International Airport, Balakrishnan was escorted away in a vehicle prepared by the Singaporean Embassy, avoiding contact with the media.
He left for Pyongyang on Thursday for a two-day trip to discuss logistics, security and other details of the June 12 summit with his North Korean counterpart Ri Yong-ho. While visiting the North, he also met with Kim Yong-nam, the nominal head of state.
Which airline Kim Jong-un will use and which route the plane will take to the summit venue might have also been discussed.
The visit seems to have been made to "fine-tune the last details about diplomatic protocol and security issues to host Kim Jong-un," a source in Beijing said.
Balakrishnan is expected to return to Singapore later in the day.
