The China’s invitation to PIA to visit China had more advantage to China than to Eritrea. China doesn’t need to spend tones of money to do miracle in Eritrea. Eritrean people are hard working people with outstanding leadership and since Eritrea is not that huge country and its population is not either, China can take advantage in showcasing its input inside Eritrea which can cascade or be an example to the rest of the baboon nations to follow Eritrea’s suit.
Eritrean people if they were not sanctioned and suffocated by the west they didn’t need a jump starter by outside.
So since the west is hell bent to suffocate it, there is nothing wrong to go around it and get the jump start it needs ala China or Russia who respect Eritrea and don’t interfere in Eritrea’s internal affairs or with whom it should befriended.
So I believe China has the showcasing its miracle inside Eritrea in mind so that the baboon nations can dump their old masters who are ruling them by remote control from Washington, UK, Germany and France.
