(Insider Stories) – Japan’s Toyota Motor Corp. will invest Y23 billion ($230 million) to construct a new engine plant in Indonesia as the car maker seeks to further strengthen its leading position in the Southeast Asia’s biggest economy.

As the domestically-focused Indonesia continues to expand at roughly 6% annually in recent years, and thanks to its relatively young population, many tipped the country to become among the world’s top ten economies by 2030.

That has lured automakers such as U.S. General Motors, India’s Tata, and Nissan to flock to the Southeast Asian nation. Existing manufacturers like Suzuki and Ford is planning to increase its investments.

Toyota, which controls more than half of Indonesia’s car market, is keen to entrench its position, announcing on Wednesday it will build factory which can produce 216,000 engines each year in Karawang, around 50 kilometers east of Jakarta.

The plant, which will make engines for passenger cars, is expected to start operations in the first half of 2016. Toyota currently has one engine plant in Indonesia, annually producing 195,000 engines.

Japanese auto makers have in recent years stepped up their investments in Southeast Asia, lured by the region’s increasing wealth and as they seek higher growth rate to help offset tepid increase back home.
