Companion notes
Chinese swimmers and coaches disciplined after growth hormone seizure and positive tests at the 1998 World Swimming Championships
This companion resolves provenance: which contemporary records support the seizure, the FINA sanctions, and the separate positive tests case. It also shows where the reporting is independently corroborated, where it comes from the same wire chain, and what the available records do not establish.
Sydney Airport seizure: the shared core across independent outlets
The strongest provenance point is the luggage seizure itself. The Independent, Swimming World Magazine, AFP-republished coverage, and BBC Sport all report that Australian customs officers found 13 vials of human growth hormone in Yuan Yuan's luggage at Sydney Airport, and they place her with the Chinese team heading to the Perth World Championships. Because these accounts come from separate outlets, not one line of copy alone, the seizure detail is well corroborated even though the AFP item may have fed later summaries. None of the reports, however, supplies customs paperwork or a court file; they establish the seizure, not any downstream legal finding. [S4], [S5], [S6], [S8]
FINA and delegation sanctions: discipline, not a criminal judgment
FINA's response is documented in contemporary BBC News, Seattle Times wire, and BBC Sport reporting: Yuan Yuan received a four-year ban and coach Zhou Zewen a 15-year occupational ban. Those same reports also say Zhou admitted placing the growth hormone in her luggage, which gives the sanction context but not a full transcript of his account. Separately, AFP-republished coverage and BBC Sport say the Chinese delegation expelled both individuals, a different authority acting on a different basis. The critical limit is that sporting discipline is not the same as criminal adjudication. [S1], [S3], [S6], [S8]
Triamterene positives: a parallel case with its own procedural boundary
The other material claim is the set of positive tests for triamterene. BBC News, the Seattle Times wire report, and BBC Sport all name four swimmers—Wang Wei, Wang Luna, Cai Huijue, and Zhang Yi—and say they were suspended pending B-sample analysis. That convergence makes the existence of the positives and the temporary suspensions reliable, but it also marks the boundary of proof: the available reporting stops at the first test and interim action. No contemporaneous laboratory report here resolves the final B-sample outcome, and nothing in these stories alone converts the positives into a team-wide doping finding. [S1], [S3], [S8]

Evidence assessment
Contemporary reporting establishes that Australian customs found 13 vials of human growth hormone in Yuan Yuan's luggage at Sydney Airport during travel to the 1998 World Swimming Championships, that coach Zhou Zewen admitted packing the drugs, that FINA banned Yuan Yuan for four years and Zhou for 15 years, and that four other Chinese swimmers tested positive for triamterene and were suspended pending secondary tests. The sources also show the Chinese delegation expelled Yuan and Zhou and that Australian officials pressed for severe penalties.
