The former Governor of West Sepik province in Papua New Guinea has sounded a note of caution about joint infrastructure projects with Indonesia.
PNG's national government is committing the country to joint roading, hydro and power projects with its neighbour, intended for the area around their common border.
PNG's Prime Minister Peter O'Neill says they see economic development as the best vehicle for solving border issues such as incursions by Indonesian military chasing Papuan rebels.
Mr Solo says he is weary of PNG entering into arrangements where it is dependent on Indonesia.
"But in the long run, we feel that we are not safe for safety risk. In terms of why I'm saying this, because when we got the problem with the Indonesian people, they can automatically shut down the whole operation and we'll have a blackout throughout the province and the country because they control the economy over there."
