Economic globalization ties nations together by countless threads.
Tips
history
From a Song ci by 戴石屏 《怜薄命》: 道旁杨柳依依，千丝万缕 — willow branches by the road, thousands of threads. The image was literal (willow withes) and later spread to mean any dense web of connections.
usage
Almost always modifies 联系 or 关系. The pairing 'countless threads' + 'connection' is so conventional that the idiom almost feels like a fixed modifier.
