Between India and East Asia, the navigation-time and distance can be greately reduced by which of the following?

1. Deepeing the Malacca straits between Malaysia and Indonesia.
2. Opening a new canal across the Kraisthmus between the Gulf of Siam and Andaman Sea.

Which of the statements given above is/are correct?

The Strait of Malacca is a narrow, 805 km (500 mile) stretch of water between the Malay Peninsula (Peninsular Malaysia) and the Indonesian island of Sumatra. From an economic and strategic perspective, the Strait of Malacca is one of the most important shipping lanes in the world. The strait is the main shipping channel between the Indian Ocean and the Pacific Ocean, linking major Asian economies such as India, China, Japan and South Korea. The maximum size of a vessel that can make passage through the Strait is referred to as Malaccamax. The strait is not deep enough (at 25 metres or 82 feet) to permit some of the largest ships (mostly oil tankers) to use it. A ship that exceeds Malaccamax will typically use the Lombok Strait, Makassar Strait, Sibutu Passage and Mindoro Strait instead. Opening a new canal across the Kra isthmus between the Gulf of Siam and Andaman Sea can save around 960 kilometres (600 mi) from the journey from the Indian Ocean to the Pacific.
