I’ve never heard of that they largely had positive relations, westerners did largely exaggerate Libya and Chinese alliance, and made lots of claims about china selling them weapons even nuclear missiles, but China couldve vetoed the bombing at the UN but didn’t. However there was largely positive relations, they were a major trading partner of Libya. Libya is only a country of 6 million people though, it wouldn’t even be the in top ten cities of China. So they were friendly with qaddafi but pretty much immediately recognized the new government and started helping them with reconstruction and diplomatic efforts
