Explanation:

The first shipments on a newly-launched railway line from the Myanmar border to the key commercial hub of Chengdu in western China were delivered last week.
Transport Corridor

• It involves a sea-road-rail link.
• This passage connects the logistics lines of Singapore, Myanmar and China, and is currently the most convenient land and sea channel linking the Indian Ocean with southwest China.
• Goods from Singapore reached Yangon Port, arriving by ship through the Andaman Sea of the northeastern Indian Ocean, and were then transported by road to Lincang on the Chinese side of the Myanmar-China border in Yunnan province.
• The new railway line that runs from the border town of Lincang to Chengdu, a key trade hub in western China, completes the corridor.
• The one-way journey saves 20 to 22 days.

Other Plans of China

• Kyaukphyu Port - China also has plans to develop another port in Kyaukphyu in the Rakhine state of Myanmar including a proposed railway line from Yunnan directly to the port, but the progress there has been stalled by unrest in Myanmar.
• Gwadar Port - Chinese planners have also looked at the Gwadar port in Pakistan as another key outlet to the Indian Ocean that will bypass the Malacca Straits.
• Gwadar is being developed as part of the China Pakistan Economic Corridor (CPEC) to the far western Xinjiang region, but has been slow to take off amid concerns over security.

Hence both statements 1&3 are correct.
