Vietnamese experts warn EVFTA tariff benefits won't last. For Shopify merchants, the lesson is clear: structured product data and AI visibility outlast any temporary trade advantage.

TL;DR: Trade agreements like EVFTA give temporary cost advantages, but Vietnamese experts now warn those benefits will erode. For Shopify merchants sourcing globally or competing against international suppliers, the durable competitive edge comes from structured product data, AI visibility, and agentic commerce readiness—not tariff arbitrage. Products with 8 or more structured attributes get cited 4.3x more often by AI shopping engines than products with fewer than 3.
Vietnamese business leaders are sounding an alarm that applies far beyond Southeast Asia. The EU-Vietnam Free Trade Agreement delivered real export growth, but experts now caution that relying on tariff incentives alone is a losing long-term strategy. They're urging investment in technology, green transformation, data governance, and traceability instead.
For Shopify merchants, this is a direct parallel to the AI commerce transition happening right now. Temporary advantages—whether from trade deals, early marketplace positioning, or legacy SEO rankings—are being displaced by structural advantages rooted in data completeness and AI readiness.
Trade tariff benefits erode as competitors adapt, new agreements emerge, and cost structures normalize. The same dynamic applies to e-commerce visibility. Your current Google ranking tells you almost nothing about your AI visibility—research shows the overlap between top Google results and AI-cited sources has collapsed from 70% to below 20%.
Vietnamese manufacturers are being told to invest in traceability and data governance. Shopify merchants face the identical imperative. AI shopping agents—whether ChatGPT, Perplexity, or Google's AI Overviews—select products based on structured, complete, and accurate data. McKinsey projects agentic commerce could redirect $3 to $5 trillion in global retail spend by 2030. The brands whose product data agents can read win that shelf. The ones that don't disappear from it.
The EVFTA warning is a reminder that advantages based on external conditions are inherently temporary. Advantages based on internal capabilities—like answer engine optimization and complete product schema—compound over time.
Structured product data is the new supply chain documentation. Just as Vietnamese exporters need traceability systems to maintain EU market access, Shopify merchants need complete product attributes to maintain AI shopping visibility. Products with 8 or more structured attributes are cited 4.3x more often in AI shopping results than products with fewer than 3.
The data requirements are specific:
Shopify's Summer '26 Edition now shows merchants their ChatGPT and Gemini performance scores directly in the admin. This visibility makes the gap between complete and incomplete product data measurable and actionable.
When Vietnamese experts urge businesses to move beyond tariff incentives, they're describing a shift from external advantage to internal capability. For e-commerce, that internal capability is AEO for Shopify—the practice of structuring content and product data so AI engines cite and recommend your brand.
The math is compelling. AI Overviews now appear on 14% of all shopping queries, up 5.6x from November 2024. When an AI Overview appears, organic CTR drops 61%. But brands cited inside AI Overviews earn 35% more clicks than brands appearing only in traditional results below. The advantage has moved from ranking to citation.
ChatGPT Shopping converts at 15.9%. Perplexity Shopping converts at 10.5%. Traditional Google organic converts at 1.76%. AI-referred visitors convert at 4 to 23 times the rate of traditional organic visitors. The channel that can read your product data is the channel that drives conversions.
The Universal Commerce Protocol (UCP), developed by Google and Shopify, is now auto-enabled on every Shopify store. The March 2026 update added multi-item carts and live catalog queries, meaning AI agents can now build complete shopping carts directly from your product data. Merchants implementing both UCP and the competing ACP protocol capture 40% more agentic traffic than those using only one.
Shopify abstracts the protocol complexity. What remains in your control is whether your product data is good enough for an agent to choose you over a competitor.
The practical checklist:
Vietnamese exporters are being told to invest in technology and data governance. Shopify merchants should hear the same message.
Vietnamese experts emphasize green transformation and continuous improvement. For e-commerce content, the equivalent is freshness. A 2026 GEO benchmark study confirmed that content updated within the last 30 days receives 3.2x more citations across AI platforms than content that hasn't been refreshed.
Product pages with benchmark data—pricing comparisons, performance metrics—are cited 2.8x more than generic product descriptions. For commercial queries, 83% of AI citations came from pages updated within the past 12 months, with more than 60% refreshed in the last six months.
The cheapest AI visibility move you can make: update your top product pages with fresh comparison data. Add current pricing context. Include recent customer review highlights. Timestamp your updates visibly.
This mirrors the EVFTA advice on continuous investment. Static product pages, like static trade strategies, lose ground to competitors who keep improving.
Vietnamese businesses are urged to build reputation through quality and traceability, not just price advantage. For Shopify merchants, brand mentions now correlate 3x more strongly with AI search visibility than traditional backlinks (0.664 vs. 0.218 correlation).
This means:
The practical implication: invest in brand mentions in AI through digital PR, expert commentary, and community participation. A single mention in a DA 80+ publication drives more AI citation than 100 low-authority links.
Vietnamese experts warn that EVFTA advantages won't last forever. For Shopify merchants, the timeline is more specific. Perplexity responds to new content within days. Google AI Overviews reflect indexed content within 2 to 4 weeks. ChatGPT and Claude training-based citations take 3 to 6 months to influence.
The Shopify Scripts deadline hits June 30, 2026—a reminder that platform transitions happen on fixed schedules. The AI commerce transition is happening on a market schedule, but the brands building AI visibility infrastructure now will have structural advantages that late movers struggle to displace.
73% of consumers already use AI somewhere in their shopping journey. 70% are at least somewhat comfortable letting an agent buy on their behalf. Only 13% have completed a purchase via AI referral so far. That gap between comfort and action is the first-mover window.
What does the EVFTA trade agreement have to do with Shopify merchants?
The EVFTA warning illustrates a universal principle: advantages based on external conditions (tariffs, early marketplace positioning, legacy rankings) erode over time. Durable competitive advantage comes from internal capabilities like complete product data and AI visibility.
How do I check my AI visibility on Shopify?
Shopify's Summer '26 Edition added an admin section showing how your products perform inside ChatGPT, Gemini, and Copilot. Check your Shopify admin for AI visibility scores and specific guidance on improving them.
What structured attributes do AI shopping agents require?
AI agents prioritize products with complete data: clear product names, accurate pricing, real-time inventory, shipping details, return policies, multiple images, fully specified variants, GTINs, brand names, and customer reviews. Products with 8 or more attributes get cited 4.3x more often.
How quickly does new content affect AI citations?
Perplexity responds within days due to real-time retrieval. Google AI Overviews reflect indexed content in 2 to 4 weeks. ChatGPT and Claude training-based citations take 3 to 6 months to influence.
What's the difference between ACP and UCP protocols?
ACP (Agentic Commerce Protocol) was developed by OpenAI and Stripe for checkout sessions. UCP (Universal Commerce Protocol) was developed by Google and Shopify for full-journey commerce. Shopify merchants get both automatically—the work is making product data complete enough for agents to select you.
Why do brand mentions matter more than backlinks for AI visibility?
Brand mentions correlate 3x more strongly with AI search visibility than backlinks (0.664 vs. 0.218). AI engines synthesize from sources where your brand is discussed authentically, not just linked.
What's the business case for investing in AI commerce readiness?
McKinsey projects agentic commerce could redirect $3 to $5 trillion in global retail spend by 2030. ChatGPT Shopping converts at 15.9% versus 1.76% for traditional Google organic. AI-referred visitors convert at 4 to 23 times traditional rates.
