Cherrypicking, you're quoting a raw number from over a decade ago without any baseline or context. China has thousands more bridges than most countries so the absolute number of incidents will be higher. The real question is what’s the failure rate

A study analyzing bridge failures in China estimated an annual failure frequency of approximately 1 in 5,000 bridges, equating to a failure rate of 0.02%.

Estimated Annual Failures: Research indicates that the U.S. experiences approximately 87 to 222 bridge failures per year the US has 623,000 bridges. So the US has a failure rate of 0.014% to 0.036%

It's worth noting that China only really started getting reasonably wealthy 20 years ago, so any bridges built before then would have been done when China was much less advanced.
