He said the two cities will continue discussing specific measures to foster bilateral ties.
On the occasion, Secretary Thang also asked the hosts to create all favourable conditions for Vietnamese investors, including those from Ho Chi Minh City.
The Lao leaders hoped that Ho Chi Minh City will increase its investment in Laos, not only in major cities but also in remote and mountainous areas.
