Southeast Asia OOH for Chinese Agencies: How to Find, Plan and Prove Overseas Campaigns

Chinese brands are expanding into Southeast Asia, and the briefs are landing on agency desks. The client wants to be visible in Vietnam, Singapore, Malaysia or Thailand, and wants to measure the campaign’s effectiveness.

Out-of-home (OOH) is an essential part of the media campaign. It builds presence in the city, in front of real people.

1. Find: Where is the right media, and who do we trust to buy it?
2. Plan: How do we choose locations in a market we don't operate in every day?
3. Prove: How do we show the client the campaign delivered?

This guide takes each in turn.

1. How to find overseas media

At home, you know the media owners, the formats and the going rates. Overseas, none of that is a given.

• Inventory is fragmented. Each market has its own owners, formats and ways of selling.
• Information is uneven. Site details and audience data are not always consistent from one market to the next.
• Buying can be slow. Separate quotes, contacts and processes across markets can add complexity and time to an overseas brief.

The practical fix is to avoid sourcing market by market. A connected platform can give agencies visibility across markets, helping them discover relevant inventory, compare opportunities and coordinate regional OOH planning more efficiently. Moving Walls operates across 50+ markets with over 1 million OOH sites, so one workflow can cover a regional brief instead of a separate search in every country.

2. How to plan: start with the audience, not the screen

A common mistake on overseas briefs is choosing media by size or familiarity. A better approach is to plan from the audience.

Step 1: Define who you need to reach. Be specific. "Young urban consumers" is too broad, but "active, fitness-minded shoppers in Vietnam's busiest cities" is a plan.

Step 2: Find where they actually are. Use footfall and location data to see where that audience moves, and when.

Step 3: Build the media list from the data. Select locations by audience concentration, then time the campaign for peak hours.

Step 4: Stay flexible. Plan to adjust while the campaign is live, rather than locking everything in on day one.

Done this way, planning becomes a story you can defend to your client. You can explain why each location is on the plan.

3. How to prove: measurement your client can trust

This is where overseas campaigns are most often judged. The client is far from the media and relies on your report.

Reports that rely solely on media-owner data can be difficult to compare across markets. Different media owners may use different measurement methodologies, making consistent campaign reporting more challenging.

Proof should be:

• Independent. It should not depend on media owner-reported numbers.
• Consistent. The same method should apply in every market, so results can be compared.
• In one place. Planning, delivery and reporting should sit on one platform, not in five spreadsheets.

Moving Walls measures campaigns on one platform with MW Measure, which tracks campaign performance with real-world attribution. The result is a report you can put in front of a client with confidence.

4. Case study: Calvin Klein in Vietnam

The brief. Calvin Klein wanted a high-impact presence across Vietnam's urban and lifestyle communities. The aim was to reach active, fitness-focused audiences in the country's busiest cities.

The plan. Working with Moving Walls, the campaign took a data-first approach. The team analysed footfall and impression multipliers to find the locations and timings where the target audience was most present.

The campaign.

The result. The campaign delivered a large-scale presence across Vietnam, with performance measured and optimised throughout the 27-day campaign.

What agencies can take from it. This is the model for a Southeast Asia brief: define the audience, plan from the data, optimise live and report with confidence.

5. Where Moving Walls fits for agencies

• Access: one connected network of media across markets
