The available evidence supports the core contrast in the claim: Reuters' report 'Chinese gold ETFs April inflows surpass first quarter total, WGC says | Reuters' confirms significant Chinese gold ETF inflows. In addition, search results for World Gold Council reports titled 'Eastern inflows counterbalance Western outflows - World Gold Council' and 'Gold ETF Flows: May 2025 - World Gold Council' are consistent with a pattern of Eastern/Chinese additions versus North American or Western declines/outflows. However, the exact wording that this specifically reflects investor responses to the 'Iran war' was not directly validated from a fetched primary page in this run, and the X post itself could not be fetched. So the statement is likely true in substance, but the geopolitical attribution remains less directly verified here.
