The evidence provided for this claim is entirely generic (Wikipedia entries on Southeast Asia, LA Metro, etc.) and does not contain any specific information regarding an 'Iran war' fallout affecting Southeast Asia's energy prices or growth. Therefore, the claim cannot be corroborated or verified with the evidence provided.

The evidence mentions US concern over tariff circumvention by Chinese exporters in Southeast Asia, which supports the general idea of tariff uncertainty. However, no source explicitly links this uncertainty to Washington's *policy* in a way that confirms the claim's specific narrative about exporters negotiating around it.

The evidence confirms that Enze Han is an Associate Professor at the University of Hong Kong and that he has published on China and Southeast Asia. However, none of the provided evidence contains his direct quote stating that Wang's visit shows China paying attention while the US has ignored the region. This specific attribution cannot be verified.

No evidence was found in the search results that corroborates the specific figure of '52%' or the context of 'last year's survey' preferring the US. The evidence provided is too general to confirm this specific historical data point.

The evidence provided contains general geopolitical comparisons (US vs. China threat perception in Europe, Nigeria's survey) but does not contain the specific data point (55.6% expecting improvement in relations with China over three years) attributed to the ISEAS survey.
