For those unaware this is what Lin is referring to ,but at the moment this phase of the Belt & Road strategy has been a huge failure for China .

Pompeo makes fun of it often if you read his interviews ,Panama is a cess pool of corruption & like in Africa etc the Belt & Road scam has been milked dry by corrupt officials causing the Chyna Asshoes to lose Billions.Also as l am also guessing Lin is referring to the high speed railway into Europe that has been a clusterfuck for China bleeding money,wrong specs used ,bridges out of alignment ,train on tests shaking so violently containers of bread dough exploded the shipping containers they were in ,electrical fittings disintegrating .
