MANILA — Philippine President Rodrigo Duterte on Wednesday sought to dispel concerns he will cling to power and become a dictator, saying he wants to achieve his goal of introducing federalism so that he can finish his term early. The former city mayor has long advocated federalism to tackle a yawning wealth gap, empower regional governments and recognize the country’s diverse makeup. A 19-member panel created by Duterte a month ago and composed of constitutional law experts and headed by a retired Supreme Court judge has proposed a federal model similar to the United States. Some critics believe the move to change the constitution to facilitate that would also provide means for Duterte to hold on to power beyond 2022, when his single, six-year term ends. But the 72-year-old said he no longer had the energy. “I will step down by 2020, I will not wait for 2022,” he said in a speech. “I am old. I have no more ambition. I really would like to rest.” Duterte’s lower house allies last month voted to convene a constituent assembly to revise the charter, scrapping mid-term elections next year and extending the terms of all elected officials. The constitution was introduced in 1987 after the ousting of late dictator Ferdinand Marcos in a bloodless “people’s power” revolution. Previous moves to change it have failed, with civil society and religious groups thwarting what they see as threats to a system designed to prevent strongman rulers like Marcos from emerging. Fears that Duterte could become an autocrat are compounded by the admiration he has expressed for Marcos. Experts believe Duterte may succeed in changing the charter because of his public popularity and the super-majority he holds in Congress. In an unrelated development, Philippines hailed on Wednesday Washington’s decision to blacklist two local pro-Daesh (the so-called IS) groups, including one which occupied the southern city of Marawi last year, triggering a months-long battle. The US State Department and the Department of Treasury designated the Maute group and the Dawlatul Islamiyah Waliyatul Masrik as “terrorist organizations” on Tuesday, blocking US-based assets belonging to them or their supporters and barring Americans from dealing with them. “The (move) is an affirmation of what Philippine authorities already know — that the Maute Group and the Dawlah-Islamiya are terrorist groups that need to be dealt with decisively using the full force of the law,” a statement by the defense ministry in Manila said. “They will be denied access to the US financial system and will face sanctions as may be deemed appropriate, making it more difficult for them to conduct their activities in the Philippines and abroad.” Militants from the Maute group were routed from Marawi last October after a five-month battle sparked by its bid to establish an IS caliphate in the largely Catholic country’s southern Mindanao region. The US, a long-time defense ally, helped Philippine forces with intelligence input, including reconnaissance flights, during the fighting which claimed more than 1,100 lives and reduced large parts of the city to rubble. — Agencies
