Person 2: “The Myanmar-China oil and gas pipelines provide a number of economic benefits. Firstly, they provide a reliable source of energy for both countries. This helps to reduce energy costs and improve energy security. Secondly, the pipelines create jobs in both countries, as they require a large workforce to construct and maintain them. Thirdly, the pipelines provide a boost to the local economies, as they generate revenue from taxes and fees. Finally, the pipelines can help to reduce the trade deficit between the two countries, as they facilitate the exchange of energy resources.”
