Leaders of the Seventh-day Adventist Church called for stronger mission involvement, strategic partnerships, and sustained prayer support as they highlighted the immense challenges and opportunities facing mission work across the Indochina region within the 10/40 Window.
Church leaders from around the division gathered during the Southern Asia-Pacific Division (SSD) Midyear Meetings to highlight the urgent mission challenges and growing opportunities across the Indochina region.
During a recent presentation, Pastor Chris Anderson, associate secretary of the Adventist church in the Southeastern Asia (SEUM), shared a sobering overview of the vast unreached territories across Thailand, Laos, Cambodia, and Vietnam, where millions still have little or no Adventist presence.
Using demographic data and mission reports, Anderson described the realities confronting Adventist mission efforts in the region. In many areas, the ratio of Adventists to non-Adventists remains overwhelmingly disproportionate. In northeastern Thailand, for example, there is only one Adventist for every 44,000 non-Adventists. In Vietnam, 27 out of 34 provinces reportedly have no Adventist church presence, representing nearly 65 million people without a local Adventist witness.
“This is the end of the earth in our territory,” Anderson said as he pointed to the vast unreached regions across Southeast Asia.
Urban centers remain among the greatest mission challenges. Bangkok, Thailand, home to more than 17 million people, has only a handful of Adventist congregations. Ho Chi Minh City, Vietnam, with more than 10 million residents, currently has only three Adventist churches serving different language groups.
“Not enough,” Anderson said. “Really, it’s only one church per people group in that area.”
Beyond the population challenge, Anderson noted that the region’s strong religious and cultural traditions present unique considerations for mission work. Thailand’s population is predominantly Buddhist, while Cambodia also has a deeply rooted Buddhist heritage, requiring the church to approach ministry with cultural sensitivity, patience, and relationship-building strategies.
Anderson explained that the strong influence of Buddhism across the region shapes many aspects of community life, culture, and tradition, making mission work a gradual process that requires relationship-building, understanding, and long-term engagement. He emphasized the importance of approaching communities with sensitivity and compassion while sharing the gospel message.
Mission work in Laos also requires careful navigation due to regulations related to public religious activities. Anderson shared that missionaries have adopted community-based approaches, including English-language centers and relationship-focused ministries, to connect with people and serve local communities in meaningful ways.
“We have to use different approaches,” he said. “Teaching English is a way of entering into people’s lives.”
The presentation also highlighted vulnerable and marginalized communities in the region, including refugee populations along the Thailand-Myanmar border. In western Thailand alone, more than 200,000 Burmese refugees live in camps with limited access to resources and spiritual support.
Anderson also highlighted the needs of displaced communities living along the Thailand-Myanmar border, many of whom face difficult living conditions and limited access to resources and spiritual support. He emphasized the importance of continuing ministry efforts that provide care, compassion, and hope to these communities.
Despite the challenges, church leaders emphasized that God continues to open doors for mission. Anderson pointed to growing opportunities among Chinese communities throughout Southeast Asia and among Muslim populations in Cambodia, whom he described as more open to relationship-building and spiritual conversations.
“There are people that are hungering and thirsting to know the truth,” he said.
The Southern Asia-Pacific Division (SSD) was recognized for its continued support of mission initiatives in the region through the deployment of missionary families, Adventist Volunteer Service (AVS) workers, and institutional partnerships.
“We’re grateful for the nine mission-focused missionaries that have been sent from SSD,” Anderson said. “We pray that as God opens a way, we can have more.”
He also noted the growing collaboration among world divisions, including support from the South American Division, the General Conference, and the Inter-American Division, which have helped provide missionary families and financial assistance for mission projects in the region.
Among the strategic initiatives currently being used are centers of influence, language schools, refugee ministries, educational institutions, church planting, and medical missionary work. Anderson also encouraged unions and local churches to adopt specific cities or mission territories to help strengthen long-term evangelistic efforts.
“We need more long-term missionaries. We need our people trained. We need scholarships where they can go and get training and come back to their territory,” he said.
He further appealed for support in translation, publishing ministries, and leadership development, especially among local believers who can effectively reach their own communities through culturally sensitive ministry.
Pastor Joni Oliveira, SSD associate secretary, affirmed the importance of mission research and strategic assessment in helping church leaders understand where mission resources are most urgently needed.
“This kind of study is actually what we hope to see from our Adventist Mission directors in the unions as well,” Oliveira said. “Can you see how valuable this kind of study is to your strategic decisions in terms of mission?”
Oliveira encouraged church leaders to continue strengthening Adventist Mission offices throughout the unions and supporting mission directors in developing focused plans for unreached territories.
As the Adventist Church continues to expand mission efforts within the 10/40 Window, leaders reiterated the need for global cooperation, prayer, and active participation from church members worldwide.
“How can you partner?” Anderson asked. “You can pray. You can come on short-term mission trips. You can provide funding for local missionaries, church planters, Bible workers, and medical missionaries.”
Quoting Adventist Church co-founder Ellen G. White, Anderson concluded with a call for unity in mission.
“We have one Bible, we have one Savior, we are one people, we have one mission,” he said. “God has called us to go to the ends of the earth.”
