Chakwera was speaking virtually from Kamuzu Palace in Lilongwe in his first statement at the general debate of the 75th session of the United Nations General Assembly (UNGA).
The session is running under the theme: 'The Future We Want, the United Nations We Need; Reaffirming Our Collective Commitment to Multirateralism--Confronting COVID-19 Through Effective Multirateral Action."
The President said:" Malawi reiterates the call for urgency in advancing reforms with full representation of Africa in line with the Ezulwini consensus of the African Union."
He said the continent needs a "UN that fully meets Africa's needs in peace process, which can only be achieved if Africa is involved in making such decisions."
Chakwera said in view of the incessant conflicts that are currently tearing down the African continent and retarding its progress, " the reforms are long overdue."
The President said Malawi's challenges are more exacerbated by geographical and related disadvantages such as lack of territorial access to the sea.
Isolation and remoteness from world markets, coupled with high transit and transport costs also disadvantage the country, the President told the 75th session of UNGA.
"All these impose constraints on our trade competitiveness and overall socio-economic development and inhibit our full participation in global production networks and supply chain," he said in his inaugural statement.
The Malawi leader then appealed for enhanced international support towards the LDCs in view of the COVID-19 pandemic, saying it was playing havoc in terms of high risk of debt default, worsening trade competitiveness, supply chain distruptions and a constrained informal working sector.
The President said Malawi being a member of the LDCs and Land-locked Developing Countries (LLDC) Groups, was among hardest-hit, "a situation compounded by a skewed development trajectory."
"We appeal for deliberate measures to ease supply chain disruptions," he said, adding that Malawi and other LDCs have large informal sectors which play crucial roles in domestic resource mobilisation through remittances and small-scale economic production.
Chakwera articulated that Malawi believes in partnership to achieve common goals.
"At this key moment for international cooperation, and during the 75th anniversary of the UN, unity is paramount towards the realisation of our shared vision of a healthy, equitable, peaceful and a more sustainable world," President Dr Lazarus Chakwera told the 75th session of UNGA .
The Malawi leader said it was for "this reason that we accepted the responsibility of chairing the Least Developed Countries (LDCs) Group up to 2022 and the Southern African Development Community ( SADC) from August 2021."
He said Malawi's membership in the African Union Peace and Security Council up to 2022 was premised on the same calling.
"Malawi is committed to make its humble contribution in all UN efforts including in the UN Human Rights Council where we are seeking membership in 2021," the President said.
He said that in keeping with the adage ' charity begins at home,' "we are committed to continue contributing a battalion of the Malawi Defence Force to the UN peace keeping mission under a SADC Force Intervention Brigade in eastern Democratic Republic of Congo."
Chakwera added: “You can count on our humble contribution towards the UN fit for purpose in the 21st century."
